One of the 56-degree guys was Rocco Mediate, I presume. Rocco's highest-lofted club is his 56.
I wonder if this information is as meaningful as it seems. I wonder, first, if the wedge lofts were determined by a quick look at the wedges (i.e., stamped/labeled "60") or if they bothered to seriously measure the loft.
There are literally dozens -- scores -- of tour players with "60-degree" wedges that are bent to 59. "60" in many cases is just the basic forging/casting that Roger Cleveland or Bob Vokey start out with when they begin bending and grinding.
I think that there are many fewer 60 and 60+ degree wedges out there.
I also wonder if, in an era of V-grooves, the USGA is anticipating a big rush among elite-level players to go to higher and more spin-producing lofts... that it may be a problem, essentially, that the USGA caused for itself through its own new groove limitation. ["No more U-grooves? Okay, I'll just get myself a 64-degree wedge..."]
And yeah, really; why not this kind of attention to the situation that really IS a big problem? Driver distance as a result of driver/ball technology.
