Re: What happen to S&T?

No offense, but you are stuck in the paradigm of "swing". There really are no swing fundamentals, but there are incidentals that when observed are given causative status.
When the club is used properly one will see some commonality of motion from good player to good player. Do not mistake that commonality as causative.
S and T is good at the set up and then breaks down from there. As far as plane, if you were swinging a hammer at a horizontal spike 3 inches above the floor in to the baseboard of a wall, would you have any thought of "hammer" plane?
