this is anecdotal, but from what I have seen, even mentioning wrist snaps indicates a PC teaches a form of mechanics that is not used by the highest level pitchers. All of the gurus I have come to respect never mention it as any sort of fundamental. I try every instruction to see how hard it is for me prior to passing it along to my DD and when I tried to coordinate the timing of a whip motion and an intentional wrist flip I find it almost impossible. If I stiff arm with a wrist flip I can control it much better. I really think a wrist flip as a foundation mechanic pushes you towards hello elbow and a lifetime of slow pitching. As they get more advanced I can see it as an add on for spins and a few extra mph but I think it would be a killer for a beginning pitcher.
