Is there any information on MPF ratings for wedges that are not made by Maltby?
There is no list of MPF ratings on Wedges. Section 12 in Ralphs book “Golf Club Fitting and Performance” explains in detail how design features in wedges determine their playability. To many wedges and not enough time to create a playability list for wedges. To be honest, there is not a lot of variation in the market today. Most different brands seem to be doing the same thing, with varying grinds, and not a lot of variation in the design features that would show a wide variation in playability, specifically sole widths, leading edge heights and effective bounce. Still, there are differences that can effect how any particular wedge might work for someone. I would encourage anyone to look at Ralph’s book. In my opinion, it explains how design features of wedges effect playability better than anything I have read.
