I am curious why the bobbing of the head on the downswing is a big deal to playing high level exceptional golf. Watching most of the great players of all time on the down swing their head lowers as the body seems to compress into the ground. Tiger and Hogan did it considerably. You wont find many that dont drop it down to some degrees in the downswing.

backswing I agree that you want no bobbing.

I think its a big thing for us club players. We don't have the talent or the time to groove and learn the compensations that are needed. You have to remember El Tigre and Ben Hogan have spent hours upon hours on the practise tee hitting ball after ball.
We are trying to learn the uncompensated stroke with TGM and the less compensations you have the better your swing and your golf will be.
