[12 piece bucket]

See, as predicted...poke Bucket and he gives up the goods! Thanks!

The right shoulder has a role to play in the downswing. The precise alignment it requires in an on plane downswing is to be "on plane"...same as hands...at least in a nonshifting downswing?

So work out what plane angle you want in downswing...then put your right shoulder in that position during the backswing...

The "flat shoulder turn" is to be used for any plane angle flatter than rotated...according to the book...

If you look at rotated shoulder players...MORAD style I think...?? there hands go pretty deep...

now I'm getting confused again...

Position of the right elbow controls plane on the backswing to an extent too . . . . Note how close Hogan's right elbow is to his rib cage versus Nicklaus . . . Note knee action and shoulder turn components too.
