Val,
This topic has already been discussed in this forum and 3jack's forum.
I have never read any rational biomechanical argument that supports the utility of any significantly overt knee flexing action, and/or waist flexing action - that would cause the head to significantly drop at the start of the downswing.
My role model is Annika Sorenstam, and she doesn't bob her head up-and-down during the her downswing.
Jeff.

Jeff,
Why do you think she tended to drop below plane and hit push draws?
I have an idea that it had to do with the length of the swing but not sure.

Greg,
Where is the "evidence" that she drops below plane?

Jeff,
Do any of your review papers cover flat versus steep shoulders, the affects of the two variations on the mechanics of the golf swing, the potential issues of each?

Greg,
No.
I have not formally discussed this issue in any review paper.
I have little sympathy for the idea that the right shoulder's downplane motion dictates the clubshaft path in the early downswing - as expressed in that LB-forum thread. I think that a skilled golfer can move the arms independently in the shoulder sockets and "slot" the power package to a shallower plane - even though the shoulders follow a TSP path.
Jeff.

That was an interesting thread and worthy of discussion. I am more concerned with the affects of axis tilt with the two variations. The affects on the swing plane on both the backswing and downswing. The affects of keeping a centered head with the two variations. Does one lead to an elbow plane impact versus the other, which is the preferred plane of tour players.

Greg,
I don't understand why axis tilt variations should determine the selected impact plane.

Greg, I don't understand why axis tilt variations should determine the selected impact plane. Jeff. If one has a ton of secondary axis tilt how do they get on a TSP impact, seems very difficult to me.........maybe a severe raising of the handle at impact from being under plane. I want to know if one backswing leads to less or more axis tilt. Does a flat backswing mack it easier to swing on the TSP or elbow plane, is it irrelevant.

Greg, I do not believe that a flat shoulder turn in the backswing affects the downswing clubshaft plane. Both Tiger Woods and Adam Scott have a relatively horizontal shoulder turn angle at their end-backswing. They could choose to come down the TSP or shallow-out to the elbow plane in their downswing. I agree that an extreme amount of secondary axis tilt will make it difficult to come down the TSP. However, Phil Mickelson comes down the TSP and he has a fair amount of secondary axis tilt in his late downswing. Jeff.
