I’ve been building clubs for about 20 years. I’ve been MOI matching for 13 years. Not many of my customers (i do this part time) are interested in MOI matching due to cost. It’s something I prefer for my clubs. I can notice a difference in my irons 4-GW on the sets I’ve built compared to typical swingweight matching. My strikes are more center contact on my MOI matched irons so I have less erratic shots and distance is more consistent. Some don’t see a difference, but no one has said change them all back to D1. Overall it’s another way to Swing weight.
The first set I did was a used set of Taylormade Supersteels. This was prior to my purchase of a MOI matching device. It was tedious, screwed up a couple of shafts (cut them short), but educational. My 7 Iron is my favorite club so all other irons are based on it. You fine tune this club for length and swing weightIf you go this route clubs are 3/8″ different in length as mentioned in your previous thread (ensure weights on each shaft are within a gram. Heads need to be 8 grams apart, use tip weights if necessary, you may need to cut off or grind down a hosel or two. If using tip weights, the length of the club will change, so you’ll need to tip trim a bit. Once everything is dry fit, you are looking for a progressive swing weight increase of approximately .5 from the Long iron to the short irons (this is tough). I’ve always had to use some lead tape to fine tune things.
In essence what you are doing is matching all your irons to your favorite iron, in my case the 7 iron. In a perfect world, you could probably fine tune all of your irons with lead tape and trim shafts accordingly and get close. You run into a problem if you have that is two heavy and you need to remove 2 grams of weight. I don’t like cutting off hosels!
It is much easier to do with the MOI Speedmatch system and the software that accompanies it. The second set I did I found an apple app called “Swingtool-Swing Weight” it measure’s MOI not Swing Weight as mentioned in it’s title. Think it was 1 or two bucks. It works and is educational.
Is it worth purchasing the Speedmatch system for just yourself, nope. If you’re doing a couple of sets a year, it works out. Would probably be best to find a club fitter in your area that utilizes the system and have it done. Other than that, a lot of reading on Tom Wishon’s site, try to download the user manual for the Speedmatch system from Golf mechanix. Dave Tutelman’s website has some info also.
