Britt, I am curious what your thoughts are and/or experience is with building a MOI matched set of clubs vs a swing weight matched set?

Back in the 1920s when the Swingweight scale was invented there was no simple way of measuring MOI available. So the swingweight scale was invented as an approximation to MOI. MOI, if measured at the center of the grip ( a point about 4 inches down from the butt end) is the true measure of Heft. Swingweight is just an approximation to that. The Swingweight approximation only works if all the shafts are identical, which they obviously are not today. None of these methods work as they do not consider ball position, club-length, or even the golfer. The scientific way of matching golf clubs so that you will groove one swing for all your clubs are called BioMatch and is available on www.rational-golf.com. You will also find a blog post on Swingweight versus MOI there.
Sasho Mackenzie did a study comparing Swingweights with MOI matching. It was not possible to tell if one was better than the other. Simply because none of them work. Another problem with MOI matching is that, for whatever reason, it is normally measured around the butt end of the club. This measurement is completely irrelevant.
