MOI Fitting

To the resident clubmakers --

Anyone have any experience with using MOI fitting instead of swing weigting? What kind of results are you getting for your customers? What is the extra cost, if any, to do it?

MOI is seen by many players as really good for feel. I have no stats on how it affects a scorecard though

Thanks, Paul.

RWH,

Go check Tom Wishon's site. He has some great information about MOI fitting. Also there are a list of Clubfitters that have been approved by his company to conduct these fittings. Wishon is THE AUTHORITY on clubmaking. If you have a chance to read any of his books, you will get a lot out of them concerning MOI and many other things.

Another thing you may want to look into is BACKWEIGHTING. I have heard this is unbelieveable. There is a company called balance certified golf that does it. But Jack had all of his clubs backweighted.

I think it would be great if we had someone with a GESD that was also a master clubfitter to help us on some of this stuff.

Good luck man!

I agree that Tom Wishon's site is an excellent place to start for getting MOI information. The MOI fitting principle is based on the idea that most folks have one or two clubs that just feel right and they hit the best. The MOI of that club(s) is measured and forms the basis for an entire set where every club is built to match that MOI. My understanding is that a consequence of an MOI built set of clubs is that the swingweight varies from club to club.

I did not want to pony up the ~$200 for Wishon's system without a little more information on how it has benefitted players. However, in my own messing around with club building and fitting clubs to my swing, my preference has been to build clubs on a shallower frequency slope (~ 4 CPM per club delta) and to also slope swingweight from low (D0 for long irons) to high (D4 or D5 for wedges). I like the extra feel I get with the heavier swingweight and more flexible wedges. The lower swingweight for the long irons keeps me from working so hard to square the face. One of these days I suspect I will go the whole MOI route since it appeals to the physicist in me.

Here is an interesting thing to read up a little on.

I am still waiting for someone to work a swing weight or MOI system based upon an individuals PP#3 position

I bought the system awhile ago, and have done my own irons only. I like the feel. Since I'm still rebuilding my swing per TGM, I can't make a fair comparison of S.W. vs MOI. However my handicap has gone down since I switched. What you have done with your swingweight would probably fall right in line with the same MOI rating. My S.W. went up as the clubs got shorter.

Sometimes a little intuition goes a long way. I am in the same boat with clubs and swing. Until I incorporate TGM principles in my stroke, I won't be able to compare swingweight to MOI either. First impressions are that there seems to be a greater consistency in feel across the set. Of course that could also be due to the fact that I weakened the flex across the board as well compared to my previous set. I did not really adhere to the scientific method here; just looking for a set of clubs I play better!

I have actually had this done 3 times. BUT, I didn't have to pay for any of the measurements.

I know the man that developed the measuring system and the software for Wishon.

I did all of the measuring (measure/remeasure and re-calculate)and building of clubs myself.

Yes, all the clubs swing the same. I have built 1 set based on the 3 iron so I could play all shots from the same ball position. That worked. I also have built 2 sets based on my favorite club - a 7 iron, and a 5 iron. That also worked.

But, all of the clubs from the favorite club (5 or 7) or the measured club (3 iron in my case) become significantly more heavy in terms of clubweight and swingweight than your standard D2 set would be.

I have had e-mail discussions with Tom Wishon about this, but we never resolved my concerns about this weight issue.

I've shot many scores in the 70's with the clubs based on the 3 iron - actually 6 weeks in a row. But I honestly don't like the extra weight.

Having said that, I haven't seen any positive remarks from several highly respected, high volume, clubmakers/fitters regarding this system (Detroit, Connecticut, Georgia). I would think that if it worked as well as Tom seems to think, these guys would be all over this.

My 2 cents.
