Constantly flipping my ideas about golf upside down. Nice work. I would like to start seeing some links to these studies you talk about, a lot of it seems to just be your word. Not that I don't trust it, I would like to read for myself though.
Christopher, what's the role of the rear hand? Do you believe it contributes nothing in terms of power to the golf swing? Why? What proof do you have of this, and what do you say to the many documents and studies which show otherwise? What do you think Ben Hogan meant when he said he wished he had three right hands (and arms)?
I have recently switched to a tighter left handed grip. My tight right hand seemed to be causing the club face to close. I could test this by just barely taking the club back 3 feet and bringing it back to the ball, in that small move the face would close. I started using more left hand and was able to bring the club face back square every time. Maybe it's just a sign that I need to weaken my left hand (as in rotation, not grip pressure). Obviously this isn't any kind of scientific data, but I always thought the left hand was key in bringing the club back to the same spot. Not saying that the right hand doesn't help some though.
Do you have any proof of this? I've gone from horrible blisters to just calluses by lightening my grip some. The grip moves no matter how tightly you grip, and the tighter your grip is when that club moves, the more damage you do, is what I would think.
