The Tour Van made a local stop, and I made a last minute decision to get a wedge fitting.  Amazing.  The experts Brad and Glenn and the Trackman took me in a different direction. The AP1 PW is going to the basement, replaced by a 48F bent to 47. They got me to 10 yard gaps and RPMs up to 9500 for better stopping power.  Got to try the S and M grinds 56 (set to 55), and the M grind was clearly a tighter pattern.  So all 4 wedges will now be Vokey, I've got consistent distances and more spin. It can't get better than that.
