Mike,

To piggy back on RCW's question . . . where would the club be pointing in step #2 based on the pronation of the right forearm? "across the line" or "laid off"?
It could be right on plane- but at this level I'm not integrating the plane - just isolating the concept of patterns of joint motions and noting the added movement/and power in that kind of backswing.
Also, when you define "hands" are we talking humerous bone, forearms, wrists, hands and fingers? You'd have to define the context of the question, but as a general answer I would say not the fingers, and the hands are the hands. However, what you try to do with your hands can create different movements in your upper arm (humerus), your forearms, and your wrists.

I agree with RCW you are "on to something."

Thanks for the questions!
