Moment of Inertia Matched Clubs

[daverollo]

Just wanted to find out if anyone had any experience of being fitted for and are using MOI matched clubs?

Have you noticed a difference (read improvement) with the consistency of ball striking throughout the set of clubs, or is it a case of emperors new clothes?

Large explanation available here for those who want to know more:

There are several ways of matching a set of clubs, of which swing weighting is the most common. This is a static measure of the lever arm about a point 12" below the top of the grip. As this is lower down the club than where most golfers grip it, the logic behind this is a bit doubtful, but it is supposed to give the best compromise between how heavy the club feels to the golfer and its moment of inertia when swung. With clubs of different length, the heads have to get heavier as the clubs get shorter. Matching could be done in other ways, such as same length clubs with the same weight heads, constant moment of inertia, or frequency matching (whatever became of that?).

Appreciate your reply Del, I understand the swing weight method, the MOI is a new one on me and have been doing a lot of reading. Essentially it is a method that is more sophisticated than swing weight to get each club feeling very, very similar in terms of how it feels when swung. Each individual will have their own MOI score as to what suits their natural swing, it might be a number like 2725. The idea then is the club fitter adjusts each club so that the MOI (2725) matches each club, effectively allowing the player to put the same swing on any club in the bag (irons, wedges, woods being different though). Using the MOI method it could actually lead to quite a variance in actual swing weight through the set, because instead of matching all irons to D3 weight, it might be that the 3 iron is D2, but the 9 iron ends up at D6 or D7.

I am guessing that their aren't many folk who have actually had experience of getting fitted for MOI clubs and then using them

I can remember when MOI fitting - probably with the advent of Wishon's tool - popped into popularity, but seems to have faded away fairly quickly. Perhaps because it needed special hardware?

Does seem a way to match clubs more 'naturally' with the swing-weight method being something of a compromise. I'm pretty certain there would be charts/calculations that allow some sort of conversion between the two.

think Golfsmith had the first 'tool + computer software' for 'whole club MOI fitting' some while back

smaller specialist fitters still do it as do companies like Muira (frequency/puring is still around but also adds to equipment cost)

MOI match never going to appear to much as yet with the mainstream manufacturers unless they find a ways of delivering it & still meeting profit margins - but is why to a lesser degree why tungsten heel toe weights have appeared as this could go further down the MOI match route

as most Tour Pro's work with finer tuned feel of motion their Clubs more include complete club MOI work (mostly all frequency matched - orientation of the shaft alignment in the head)

going back some that's why so many Tour Pro's clubs used to be seen with lead weighting, to match complete club MOI feel club to club

Clubs Ryan Moore uses, PXG's, perhaps the most extreme example of MOI match fit to date - one reason to why the clubs are also a ways expensive

I believe that MOI is essentially matching the moment arm from the mid gripping point, say about 5" from the top of the grip. Hence longer irons will need lighter heads and shorter irons will need heavier heads. So suggest you try adding some lead tape to your short irons to see if you hit better shots. I have done this to my wedges and 9-iron and they seem to swing better.

This article could help provide a way to change a SW set to a MOI simply by using some lead tape!

Appreciate the responses folks, what I am ideally looking for is someone who has experience of actually using MOI matched clubs and what the results were like.

My next set of clubs will be custom built, likely to be by these folks http://www.appliedgolftechnology.co.uk/ and having them MOI matched is an option OR they can do it to your existing clubs.

AGT are certainly one of the recognised top fitters around!

The obvious thing to do is to discuss the pros and cons with them!
