Is there such a thing as MPF ratings for drivers, if so where can it be found. Thank you
Ralph’s intent was to do an MPF rating system for drivers too, but realized that there simply is not enough distinction that can be made in drivers since all were 450-460cc’s and with variations (he measured at the time) not being significant enough to clearly distinguish a real playability difference from one to the other. Irons are completely different with a wide range of variety in shape, mass distribution, dimension, etc. Basically all modern drivers are Ultra Game improvement designs. If you wanted to look at it theoretically from a historical standpoint, we could say that persimmon woods would have in the players classic category, the first metal woods would have been in the classic category (different material, but same size and weight), the introduction of the first Big Bertha would theoretically be in the Game Improvement category (360 cc head size) and then when the head size jumped to 460 cc they would be in the Ultra Game Improvement category. It would be a monumental task to try and measure current drivers, with all he adjustability available, and try and find any element(s) that clearly indicated one was more playable than another. Of course, for each individual there are certain drivers that could work better for them than another, but doubtful it would be because the mass and dimensional characteristics are significantly different. It most likely will be the specs of loft, face angle, shaft choice and flex profile, length, etc. fit them better in one driver vs another.

thank you
I would be interested in this also. I found in Maltby’s “The Complete Book of Golf Club Fitting & Performance” that the formula is similar, but heavier emphasis is placed on MOI. Also at the time of print, his formulation was 95% complete (print issue 2011). Not sure if that has changed over the past 8-9 years.
