Srixon and Ben Hogan clubs now have V soles with both leading edge and trailing edge bounce. How would one determine the effective bounce on a club that has say, 23* leading edge and 6* trailing edge bounce?
Without having the specific clubs to measure, I can’t tell you the precise number. I can tell you that when you have a split sole, the only part of the sole that is a factor is the leading edge side of the sole. Basically splitting the sole greatly limits the effectiveness of the sole angle in the performance of the club, in my opinion. Bounce, or sole angles true actual measure is in the center of sole. Ralph wrote at length about sole angle on wedges in his book “Golf club Fitting and Performance”. Section 12 covers wedges. The same concepts on sole angle that apply in wedges apply to the other irons in a set and I think if you could review that material you would have a better understanding of the soles role in performance and why split soles are reduce the effectiveness of the sole.
