I'd like to ask a question....how does the "karate chop" relate to a sweep release?
Kinda does and kinda doesn't . . . if you are using Standard Wrist Action you want your right plam up to the plane and left palm facing the plane. With a snap release you are going to keep that alignment FEEL as if there were no release at all. With a sweep release you still will have the alignment you will just not drag it down as deep and steep. More of a circle type feeling than a straight line deal.
Yes, the "quick" feeling of hitting before the backswing is complete actually gives me a heavy feeling throughout the swing. Is this the "quick" that is being talked about?
