51 Orlando Area Courses to Play

With winter here I wanted to go thru the entire list of golf courses in Orlando that I have played that are available to the public for play for those golfers looking to play golf in the area in the next few months. These courses are in alphabetic order and most can have their tee times booked at Some courses I have left off the list is due to having not played there since moving to the area in 2010 (I played these courses in the 90’s; i.e. Timacuan, The Claw at USF, etc). I have ranked the courses on a scale of 1-10. 5 is considered ‘average.’

1. Bella Collina CC – Used to be an exclusively private course designed by Nick Faldo. One of the hilliest courses in all of Florida. Features a $50 million club house and plays to 7,900 yards from the back tees. Difficult to figure out where you are going the first time you play it. A little too long with too many uneven lies for my tastes. 18th hole is ridiculous. 5.5/10

2. Black Bear GC – Used to be a premier course in the area although it is located in Eustis which is nowhere close to anything. Pete Dye design. Very long and some very unfair driver shots which is common for Dye. Was not in good shape when I played it last year, but I think it’s a course if you play it a couple of times it can grow on you. Not meant for the higher handicappers. 4.0/10

3. Celebration GC – Designed by Robert Trent Jones’ son. It’s in Celebration which is down the road from Disney. Gorgeous housing around the course. Front nine is a bit goofy in its design. Back nine is excellent. 6.0/10

4. Champions Gate (International) – Designed by Greg Norman and is where they held Champions Tour Q-School qualifier. Very difficult course on the front nine which is very tight. Back nine is very open and very links style. 6.0/10

5. Champions Gate (National) – More of a parkland style of course and much easier than the International course. A few holes are a bit goofy in design and the course is not nearly as in good of shape and the international course. I believe it’s due to the layout not allowing the rain, wind and sun to set on the grass properly. 5.0/10

6. Continental CC – Located near The Villages in Wildwood. Very short course (only 6,300 yards from the back tees), but very tight. Usually greens are in good condition, but very slow. Back nine is much better than the front nine. 3.0/10

7. Deer Island CC – Located in the middle of nowhere. After we played the course the nearest place to eat is about 15 miles away. Overall a very nice course with a lot of scenic views. No real goofy holes and in good condition. 6.5/10

8. Deltona Club – Located in Deltona which is close to DeBary and Sanford. Great design and last time I played there the greens were in great shape. Still struggling with the tees and fairways. Usually very cheap to play there and a fun course to play. 6.0/10

9. Duran Golf Club – Located in Viera and down the road from the Stadium where the Washington Nationals spring training is played. A course with a large membership. Since it is near the coast the terrain is very flat. Decent design and in decent condition. 5.0/10

10. Eagle Creek GC – Located on Narcoosee Drive, right down the road from North Shore and Lake Nona CC. Very fair course and when I played there the course was in excellent condition. Heard they had condition troubles this year. Still, I will base it off when I played there. 6.0/10

11. Eagle Dunes – Located near RedTail in the Clermont/Monteverde section of Orlando. Starts off as hilly on holes #1 and #10, but flattens out quite a bit from there. Very so-so design and conditioning. 4.0/10

12. Eastwood GC – One of my former home clubs. Plays about 7,300 yards from the back tees. One of those courses that grows on you if you play it a handful of times. Too many poorly thought out design features (#2, #4, #6, #8, #10, #12, #13) and too many greens designed like a potato chip. Heard that course conditions have worsened. Depending on the day one can play a super fast round or a super slow round. Located near UCF. 3.0/10

13. El Diablo G & CC – Designed by Tom Fazio’s brother and located up near Ocala. Very difficult course but a fairly good design. Course was in rough condition when we played it. Overall enjoyed it but it’s not a confidence builder. 4.5/10

14. Grand Cypress (new course) – ‘Inspired’ by St. Andrews. Each green is a ‘double green’ and there is hardly any rough. Even if you’re 100 yards off line, it’s all fairway or green or tee. Filled with pot bunkers. Fantastic condition and a treat to play. Right in the heart of the golf area of Orlando (Central West or Southwest Orlando). 8.5/10

15. Grande Pines – Located in the same area as Grand Cypress (not part of the same company). It’s in a resort/time share area but it is not anything like your typical resort style of course. It’s actually quite narrow and has some demanding tee shots. Generally a great course although a couple of the holes were a bit wacky in design. In fantastic condition. 8.0/10

16. Harbor Hills – Located near The Villages and is a course that typically has members from the surrounding community as golfers. Some incredibly demanding shots, particularly from the back tees on #10. Very solid golf course here. 6.0/10

17. Hawk’s Landing – Located in the ‘golf area’ of Orlando. Extremely weird entrance as it is part of a time share, hotel and convention center. They give free valet parking if you’re playing golf. Course is in excellent condition. The front nine is a little tricked up for my tastes, but I thought the back nine was superb. 6.0/10

18. Juliette Falls CC – Located 10 miles west of Ocala. Was a private course but now accepts tee times on GolfNow. Excellent course. If there is a complaint, the par-3’s are nearly impossible from the back tees. Otherwise some outstanding golf holes and a great atmosphere for golf and being able to have some food and drinks afterward. One of my favorites and well worth the trip. 9.0/10

19. La Cita CC – A hidden gem located in Titusville. It’s a private course that you can only call to make reservations. Winter rates are pricey, but it’s a Ron Garl and Lee Trevino design. Features a lot of dog legs. First 6 holes could be better, but holes 7-18 are as strong of a design as anywhere in Orlando. Usually greens are in good shape, tees and fairways leave a lot to be desired. 6.5/10

20. Legacy Club at Alaqua Lakes – Private course that you can only book tee times thru Located near Lake Mary and is a Tom Fazio design. Tough course in general, but open to some low scores if you hit it well. Generally in great condition. New ownership should take the conditioning to the next level. 8.0/10

21. LPGA International (Hills Course) – World class facility where the LPGA Q-School is hosted. You will see a lot of mini-tour and junior golfers here. The Hills course is the better of the two and much more difficult. Fabulous design by Arthur Hills. 8.5/10

22. LPGA International (Jones Course) – This course was designed by Rees Jones and is a much easier design. No real bad holes here, but nothing that stands out like they do on the Hills Course. 6.5/10

23. Metrowest GC – Located on the west side of the city about 10 minutes from the Amway Center. Robert Trent Jones design that has its fair share of hills. The 14th tee is the highest point in Orlando. Recently renovated with $1.5 million which made the course much easier, but much more fun. They also installed TifEagle greens, my Bermuda green of choice. 7.5/10

24. Mission Inn (El Campeon) – One of the best courses in the area that is home to the Gary Gilchrist junior golf academy. It doesn’t look like it when you get there, but the course is extremely hilly. It was designed in 1917 and it has the feel and design of an old school PGA Tour course before the Tour went to all of these TPC designs. And because of the hilly landscape, it feels like a top tier course in a more elevated area like Western Pennsylvania. Generally in very good shape, but not in top-tier condition. 8.5/10

25. Mission Inn (Las Colinas) – Designed by Gary Koch and redesigned recently. The front nine is excellent. But, the back nine becomes incredibly narrow. The narrowness of the back nine is surrounded by trees, but it is too narrow that there is not a lot of strategy and overwhelming skill. It becomes more about luck. 4.5/10

26. Mystic Dunes – Designed by Gary Koch. Reminds me a bit of a Mike Strantz design where it is more about art than golf (which isn’t necessarily a bad thing). The only thing I didn’t like about the course was the green designs which left for some ludicrous putts. One on hole with a giant tier in the green that ran from the front to the back (splitting the green in 2) we actually thought the flag was cut off the green. Outside of the 18th hole, the holes were fairly logical in design. 5.5/10

27. North Shore – Located down the road from Lake Nona and Eagle Creek. Has great TifEagle greens. The front nine is more of a links style course and the back nine is more parkland. Generally a fun course to play and it can yield some low scores. Pace of play is often horrendous there. 6.5/10

28. Orange County National (Crooked Cat) – Another world class facility that hosts the demo day for the PGA Merchandise show. Has the largest range in North America. Probably the best conditioned public course in Orlando, particularly in the winter. Crooked Cat is the easier of the two. It’s much more reasonable, but doesn’t quite have those great holes. 7.5/10

29. Orange County National (Panther Lake) – My only gripe is that there is some confusion as to where to tee off between the 3rd hole and the 7th hole. It also has a couple of tee shots where you have to hit it 260 carry from the back tees in order to have a chance. Other than that, it’s excellent. 9.0/10

30. Orange Lake Resort (Legends Course) – Arnold Palmer design and one of the best designed courses in all of Orlando (including Bay Hill). Usually in terrific condition and features wooden flag sticks. Not a bad hole on the course. It is a bit loud because of the resort. 9.0/10

31. RedTail Club – Located in the Monteverde area and is a bit of a trip to get out there. However, this is a very fun and well designed course. The best part is the design of the par-5’s. The back nine is a bit more difficult. Great club house and nice finishing hole. Conditioning took a bit of a hit this year, but still in pretty good shape. 8.5/10

32. Rio Pinar CC – Typically a private course now offering tee times on GolfNow. Built in 1957 and has that feel of an old school Tour course as it is where the PGA Tour used to hold the Citrus Open. Requires better driving of the ball than most people think. Currently going thru a $4.5 million renovation with new, Championship Bermuda greens. The facelift was much needed. One of the most fun designs in all of Orlando. If the newly installed greens play well, the ranking would be higher. 7.0/10

33. Ritz Carlton – Grande Lakes – World class facility and treatment from the staff. Recently held the PNC Father/Son Challenge there. Course is in phenomenal condition and is mostly filled with well designed holes, but nothing that leaves you with something to remember. And if the conditions are not in your favor (either rain or wind), it can be pretty brutal out there. 8.0/10

34. Shingle Creek – Excellent course design that is not too resort-ish and won’t beat you up either. In the winter time the greens are in superb condition. This is not too far from Universal Studios and they take good care of the customers here. Some really excellent holes here like #3, #4, #9, #11 and #15. 8.5/10

35. Southern Dunes – Noted for having the best greens in Orlando and I have to agree. About 15 minutes south of Disney and a very nice parkland style course. Played there in the Summer and the greens were smooth reading at 13 on the stimp. Lovely course and layout with a lot of fun golf holes. 9.0/10

36. Spruce Creek – Located up towards The Villages. Front nine is very short (about 3,000 yards) and back nine becomes longer (about 3,500 yards). Quite a few wacky holes with very sharp doglegs, but it also has a lot of good holes. One of those courses that if you play it a few times it will grow on you. 4.0/10

37. Stonecrest – Located near The Villages. Another course that if you play it more often that it will grow on you. Starts out tough with a par-5 that has two large fairway bunkers right in your landing area. Then a 210 yard par-3 into a small island green. Then the next few holes feature a lot of weird terrain. 4.5/10

38. Stoneybrook East – Located near UCF. Very tight course that has water and hazards surrounding both sides of the hole. Not overly long. Typical Clifton and Ezell design in that it’s a nice course from tee to green, but some ridiculously designed greens. If you can drive it well, you can go low on the course. Type of course where I could shoot 68 one day and then 86 the next day. TifDwarf greens which means that they are in inconsistent condition. 6.0/10

39. The Villages (Arnold Palmer) – 27 hole design by Arnold Palmer. Typical Villages course in that it has a nice design from tee to green, but the greens are very slow and very undulated. Better hit it well to shoot a low score. 7.0/10

40. The Villages (Cane Garden) – 27 hole design. I cannot remember which nine is which, but one of the nines was very goofy. The other 2 nines were quite nice, forgiving and fun. Has had problems with the condition of their greens. 5.5/10

41. The Villages (Evans Prairie) – Best designed course in the Villages. The one course that does not feature slow, undulated greens. Brand new course that needs a little more time to mature. 7.5/10

42. The Villages (Glenview) – Perhaps the most difficult of The Villages courses. Not as well designed as the Palmer course or Evans Prairie, but still a very solid course. 6.5/10

43. The Villages (Nancy Lopez) – 27 hole design by Nancy Lopez. A little less sever on the green slope and is generally well designed. 6.5/10

44. The Villages (Tierra Del Sol) – One of the first courses at the Villages. Has a lot of decent holes, but too many poorly designed ones. It’s also in fair condition compared to the top courses in The Villages. 4.5/10

45. Venetian Bay – Located near Daytona Beach. A course with a fairly good sized membership. Very flat and I found this course rather dull, but in good condition. 5.0/10

46. Victoria Hills – One of the best designs in all of Orlando. Just a fun, interesting and well thought out layout. Located near Sanford. Tees and fairways are in so-so condition, but the last time I played there the greens were in excellent shape. Some great par-5’s on this course. 7.5/10

47. Viera East – Located a bit north of Melbourne. A decent front nine design that improves dramatically on the back nine. Decent conditioning. 5.0/10

48. Walkabout GC – Located north of Titusville. Fairly hilly for that part of Florida. Pete Dye design with holes 1-12 being as tough of a stretch as anywhere in Florida. Building a 25,000 square foot club house. In good condition in the winter. Bring plenty of balls. 5.5/10

49. Windermere CC – Private club now accepting tee times at GolfNow. I think this would be a nice course to be a member at. But playing it I was not blown away by it. Good conditioning and I thought the back nine was a very good design. 5.5/10

50. World Woods (Pine Barrens) – Ranked in the top-100 in Golf Digest. It’s a hike to the middle of nowhere to get there. Course was designed by Tom Fazio as a tribute to Pine Valley. Dramatic and beautiful landscape. Top course I’ve played in the area. 9.5/10

51. World Woods (Rolling Oaks) – Fazio designed this course as a tribute to Augusta National. The excellence of Pine Barrens overshadows the greatness of Rolling Oaks. Some of the finishing holes are a little unfair, but otherwise a great course. 8.0/10

No Ground Reaction Force Swing

Here's a video from 3Jack Top-50 Instructor, Chris Como. The idea is showing what a golf swing would look like without any 'Ground Reaction Force.' In other words, what the swing would look like if a golfer could not use the ground.

What's particularly interesting is how much rotation plays a part in this. As we can see, there's not much rotation in the swing that Chris tries to provide.

And if you look at his hip rotation in the downswing, it actually goes in the opposite direction as he swings through.

MOI & Balance Matching FAQ's - Part III

Doherty states in his MOI Balance Index Spreadsheet that he was able to change his club path with the Balanced clubs. Is this really possible?
I do not believe that this is really possible.

For instance, if a golfer has a path that is -4° left of the target I do not see it suddenly changing to +2° right of the target.

At least I do not believe that Balancing a set of clubs is directly related to the path. I think that MOI matching helps the path become a little tighter in dispersion, thus the smaller impact dispersion when clubs are properly MOI matched. For instance, I feel a golfer whose path ranges from -3 to -9° left with a swingweight matched set of clubs may go to -3 to -6° left with MOI matched clubs.

Mind you, I have no actual evidence of that. However, I have good evidence that impact dispersion greatly improves with clubs that are properly MOI matched. Thus, I am theorizing *why* that is.

Doherty states in his spreadsheet that he was seeing distance gains with his clubs Balanced. Is this possible?

Yes, I believe so. With a 3-iron that is not Balanced, the club already has a low loft. So if we hit it low it will not go as far. And if the club’s mass is more concentrated in the shaft, it’s just going to launch lower.

Conversely, with a PW the club has more than enough loft to produce a high launch and spin ball flight. With the club’s concentration of mass more in the club head, the ball will just be launched higher and spin more. With the clubs properly balanced the launch and spin conditions become more ideal for each club.

How much does this really help?

Here’s a Trackman record of Tour averages. Pay close attention to the Max Height column:

The max height for clubs should roughly be the same. But even the Tour players have some difficulty accomplishing that.

The lowest flying club?


We see the 9-iron and PW fly lower than the 7-iron. However, the point is that Tour golfers have to alter their swing mechanics to hit those short irons lower and the long irons higher. From my experience, I feel it is easier to produce lower ball flights than higher. I can easily knock a shot down lower than normal than to try and hit one noticeably higher than normal.

With Balancing the set, the clubs are designed so the golfer doesn’t have to make wide sweeping changes in swing mechanics to hit their long irons high enough and get that penetrating ball flight with their short irons.

How would counterweighting work with Balance matching clubs?

We have to remember that with clubs here are the rules of thumb as far as weight added at certain locations and how it changes the club's MOI:

1-gram to club head = 10-12 MOI points

1-gram to balance point = 5 MOI points

1-gram near shaft label (below grip) = 2-3 MOI points

1-gram on butt-end of shaft = 0 MOI points

Let's say we have this scenario here where our 9-iron is assembled and we are trying to reach a target of 2,725 kg/cm^2 and a Balance Percentage of 60%.

balance 3.png
If we add 3.5 grams of lead tape to the head, that will get us to 2,725 kg/cm^2:

Balance 4.png

However, that lowers the balance to 55.18%.

What we know is that if we were to keep the head weight at 284.5 grams, that 60% of that would be 170.7 grams. 

And since our grip weighs 49 grams, that means the shaft needs to weigh 121.7 grams.

In this scenario, if I were to add a 12-gram counterweight, the components would now look like this:

Balance 5.png

Now, that is not at 60%, but we have a +/- 2 % margin of error to work with. 

Earlier you mentioned that you found that counterweights can often be used in the driver, 3-wood, short irons and wedges.  Why is that?
Aerotech, Nippon and now UST with the Recoil line of shafts appear to be seeing the flaws with swingweight and swingweight matching and are now favoring MOI matching.  But, every other shaft company is deeply entrenched into swingweight matching.  And the OEM's that make the drivers, irons, wedges, etc are the same way.  So the way many clubs are designed with swingweight matching in mind makes them a bit more in need of adding shaft weight in order to balance the club.

I will start with the driver.

Generally, the driver is not a giant issue if the club is designed to spec.  But, the typical shaft lengths of a driver are 45.5" to 46" long.  The shaft's weight and Bend Profile may fit the golfer just fine.  But, it's length may present an issue.  The golfer may have way too long of a driver shaft and now their alignments at address are thrown off.  They'll either end up having too little waist bend at address or they will stand further away from the ball to get that waist bend.  Both of which can set off a lot of compensations to be made in the swing.

So if the golfer wants to fit their driver closer to their height and arm length, they will likely need something in the 44" - 44.75" long range.  In fact, Bubba Watson and Adam Scott, two fairly tall golfers, use a 44.5 and 44.75 inch drivers respectively.

The problem is that just trimming the shaft from the butt end will present some MOI issues.  The MOI will become much lower.  Again, that shaft's weight may have fitted you nicely at 45.5" long, but at 44" long the weight and the heft changes.  And if you like the shaft's Bend Profile you will either need to find a shaft with a similar bend profile that is heavier in weight or use a counterweight. 

I believe that OEM's have struggled to make 3-woods with the correct amount of heft.  Your typical driver head weighs about 200-205 grams.  Your typical 3-wood head weighs about 207-212 grams.

But, the typical driver is 45.5" long while the typical 3-wood is 43" long.  That's a giant difference in shaft length while only having about a 7-gram difference in head weight.

The normal head weight discrepancy in *irons* is 7-grams.  But, irons are only in 1/2" or 3/8" shaft increments.  Here we have a 7-gram increment from teh driver to the 3-wood, but a 2.5" shaft length difference.

The typical adjustment made is that the golfer will use a similar shaft to their driver, but about 10-grams heavier.  I just do not believe that the difference in weight makes up for the 2.5" shaft length difference (or even a 1.5" shaft length difference).

The issue with short irons and wedges is that virtually no matter how heavy of a shaft you use, the shaft will not be heavy enough once it is trimmed.  I purchases a 138 gram wedge shaft, the heaviest I could find, and after trimming it only weighed 110 grams.  And I needed a 122 gram shaft weight.  The same with the shorter irons, except you can get away with using less weight in the counterweight.

In the end, I think this is something consider if a golfer is seeking the ultimate in club fitting and trying to figure out why some clubs either do not feel or perform quite like other clubs in their bag.  And I really think that it can provide a giant benefit to golfers looking to hit their driver better if they are willing to patiently try out different scenarios.

MOI & MOI Balance Matching FAQ's - Part II

In part II I will go over the FAQ’s involved with ‘MOI Balance Index’ often referred to as ‘balancing’ clubs.

What is MOI Balance Index?

MOI Balance Index means that the clubs are MOI matched *AND* the static weight of the components of the club (shaft, grip and head) are in the same proportion. The concept of MBI was developed by an engineer named Monte Doherty. He created an extensive Microsoft Excel spreadsheet to help determine MBI. It not only accounted for the weight of the components, but the Center of Gravity of each component.

Have you ever heard of the ‘balance point’ of a shaft? If so, Doherty’s spreadsheet accounts for the balance point of the shaft as well as the balance point of the grip and the type of head (driver, fairway wood, hybrid, muscleback iron, player’s cavity back iron and Game Improvement iron). Between that and the weights of the components, he created a MOI Balance Index number. The number ranges from 0-100. In reality, the number will range more from 30-70.

I don’t understand what you mean by ‘weight of the components being in the same proportion. Can you explain?


Here’s a table of the weight of the components of a set of irons that are swingweight matched.

What many golfers don’t realize is 2 things:

1. Head weights gets progressively heavier as the club has more loft.
2. Shaft weights (trimmed) get progressively lighter as the club gets shorter

Clubs have been designed this way since the beginning of swingweight. When you trim a shaft, the shaft’s static weight becomes lighter (less shaft = less weight). So in order to counter those shafts getting lighter, OEM’s make the heads heavier as the club gets shorter.

However, that causes the proportion of the weight of the clubs to change. When we take the shaft + grip weight and divide that by the head weight, we see dramatic differences. The 3-iron percentage is at 65.1% and the Pitching Wedge percentage is at 51.1%.

So, with ‘balancing a set of clubs’, the percentage would be roughly the same. Let’s say we wanted to match everything to our 6-iron (58.5%), the table would look something like this:

Why is Balancing the set important?

It’s certainly not mandatory to balance a set of clubs. However, the main benefits are launch and ball flight. Provided that you are fitted for Balancing a set of clubs, the concentration of the club’s mass will be roughly the same.

In this set that was not balanced:

We have a 3-iron where there is a higher concentration of the club’s mass in the shaft (65.1%) than with the Pitching Wedge where the concentration of mass is more towards the head.

Now, let’s go back to our example where we want to use the 6-iron’s Balance Percentage (58.5%).

The 3-iron (65.1%) will have a higher concentration of its mass in the shaft. That will produce a lower launch and spin than the golfer is fitted for. And the issue with the 3-iron is that it already has a low loft and does not need to launch lower.

Conversely, the pitching wedge (51.1%) will have a higher concentration of its mass in the head. This will produce a higher launch and higher spin. But, the club already has enough loft to produce that.

To counter their clubs being un-balanced, golfers (even Tour players) will often alter their swing mechanics to get the long irons up in the air and their shorter irons to have a more penetrating ball flight. With Balanced clubs, that requires less of that altering of swing mechanics to produce your desired ball flight.

Do we Balance all of the clubs or just the irons?

Each club can be set to the same percentage, from the Driver to the Lob Wedge. In fact, I feel that the largest benefit of Balancing the clubs is with the driver because that is the club where launch, max height and spin rate is the most important.

Do I have to use Doherty’s spreadsheet to Balance my clubs?


I find that as long as the clubs are MOI matched you can simply figure out what your target % is and then derive how much the shaft + grip should weigh. You may be off a little, but we have a margin of error of +/- 2%.  Doherty's spreadsheet helps account for more finite details like the Center of Gravity of the components.

Won’t this make the clubs super heavy if both the shafts and head ascend in weight?


If we harken back to our discussion on MOI matching; if we match our MOI in our irons and then measure the swingweight, the swingweight will increase as the club gets shorter. So if one were to use the swingweight method with balancing their clubs, they would find that the swingweight gradually increases. But since swingweight does not accurately depict heft, the heft of the club would not change if clubs are balanced properly and the MOI matches.

So how does one get ascending shaft weights since shafts get lighter as you trim them shorter?

First, we are starting to see to see major shaft companies addressing this issue with equipment. Nippon shafts have made ‘constant weighted’ shafts where the shafts remain the same weight after they are trimmed (margin of error of +/- 1 gram). Furthermore, Aerotech has created a model of shafts called the Player Spec and UST has created the Recoil model of shafts that ascend in weight. I believe that we will start to see more and more companies go in this direction.

However, there are a couple of ways to do this.

For starters, you will need access to Wishon’s Bend Profile software. If you’re being fitted with a 6-iron, which I recommend, it’s likely that the shaft fitted for the 6-iron will be too heavy in the 3 & 4-irons. If so, you will need to find a shaft with a similar bend profile that is lighter in weight to install into those clubs.

From the clubs that require heavier shafts, there are a couple of options.

For starters, one could go into the Bend Profile software and look for heavier shafts with similar bend profiles.

The other part is to add weight to the shaft. Either via a counterweight, an internal shaft weight like the Tour Lock Opti-Vibe or using lead tape to place on the shaft.

Chances are you will likely need to do this with the shorter irons because if the irons are going to ascend in weight you will probably not find a heavier shaft that is heavy enough. For instance, I’ve taken 133 gram wedge shafts that weight 108 grams when trimmed to SW length. And if the SW shaft needs to be 120 grams, then you have a problem.

The best method is to add weight to the shaft, either thru lead tape, a counterweight or the Tour Lock Opti-Vibe.

Do we have to measure the weight of the ferrule, epoxy, grip tape, etc?

For most accurate measuring, yes. 

The ferrule will weigh about 1.0 to 1.5 grams.  The epoxy weighs about 0.3 grams.  Grip tape will measure about 1 gram per wrap.  So if you put 2 wraps of tape, it will weigh roughly 2 grams.  With the epoxy and ferrule, we just count that as part of the head's weight.  The grip tape would count as part of the grip's weight.

How does adding weight to the shaft affect the club's MOI?

It depends on where the weight is added.  The closer down the head, the more it adds to MOI.  General rule of thumb is:

1-gram on balance point of shaft = 5 MOI points

1-gram near shaft label (below grip) = 2-3 MOI points

1-gram on butt-end of shaft = 0 MOI points

So, how does using a counterweight work?

Since the counterweight is on the butt end of the grip, it will have little affect on MOI.  IIRC, 1-gram of weight on the butt end of shaft equals about 1/400th of a MOI point.

Tour Lock makes a counterweight called the 'Tour Lock Pro Counterweight.'

They also make a product called the 'Opti-Vibe.'

The Opti-Vibe is *not* a counterweight.

It is called an 'internal shaft weight.'  It is a weighting product that the installer can put into the shaft thru the butt end and then move the weight up and down the shaft depending on how much MOI they want to add.  The further down the shaft they move the Opti-Vibe, the more MOI it adds to the club.
