I had same thing done at the pro shop with my Snap Lock, sanded to 4000 abralon and then polished. Much better, still plenty of hook and occasionally goes Brooklyn at a bit lower ball speed than my desired shot. The pro shop operator I go to, did the exact same thing with is Snap Lock as well and finds it performs much better.
I also did exactly that with my Alpha Crux too, 4000 abralon and polished.
