I agree that the club should not go below the right forearm. Even though Floyd started the shaft too low as you said, he corrected this by shifting to a more vertical plane at the top by lifting his right shoulder after the flat initial move. I also like where you're going with the more vertical post-impact shaft. The current fad is swinging the hands way too far left. I look forward to the post-mod videos.

I read on another golf website that guys who swung the hands "left" post impact could not putt. The people that the website cited included Sam Snead, Sergio Garcia and of course, the inimitable Ben Hogan.

Ball striking alone does not make good golf - it is merely one part of the puzzle.
