.... but Tiger often appears to slip back into adding a bit of 'hit' with the right arm, appearing to put his clubface control in his right hand at times to save the shot.

Ed,
It seems to me that this has been the crux of his problem forever. He uses that initial rotional speed from his hips and then almost requires the right arm to catch up, that interferes with cf and he manipulates the hands to square the face. It becomes more of an issue with the driver... I think he'd be a huge candidate for TGM... he is analytical as all get out, and if he understood what was actually happening I believe he'd be able to change... instead of adding compensations, which is what he always appears to do. Am I close?
