Thanks Daryl, don't get too hung up on my comment above. This was just me experimenting with a motion, not my desired pattern, purely for the sake of discussion. Going to the opposite extreme of JUST moving the right shoulder down with no rotation.
What I wanted to discuss was Hogan's ( and maybe Sergio's - thanks Lagster!) shoulder movement which seems to have alot of rotation before the down.
It would appear - again from me just experimenting in front of a mirror - that early shoulder movement alone causes a steep delivery path and as long as you "time the down" movement of right shoulder you can take the hands to a max trigger delay position with shaft parallel to plane line. It avoids clubhead getting "stuck" behind - maybe?
Gentlemen,
Keep in mind,
I do not believe, and I could be wrong, that Homer relegated the right shoulder ONLY to Swinging...
