Couple of comments:
1 I do not believe the "practical range" of fore and aft ball positioning for any given club is "wide" enough to trigger these other concerns.
2. please examine Hogan's atance/ball position drawings-page 125, Five Lessons. I can't copy the drawing.
Pay particular attention to:
He moves the ball back for each club by narrowing his stance and opening his stance.
He effectivly rotates his plane line and maintains his target line when he op-ens his stance.
Sugestion - I believe HK has included this info- maybe in bits and pieces- As we find those bits and pieces we should include them here.
