Virge, that makes sense. I dont feel like i do anything with my hands at the top except feel the cup in my left wrist, yet the flattening still happens. You would think if anything, that feeling of creating a cup would be more likely to create a steepening than a shallowing....but it doesnt.

Ray, I have no idea how Dustin Johnson hits the ball so far with such a strong left hand grip and so much bow in his left wrist. I cannot hinge my wrist to generate any angle between the shaft and left forearm if my left wrist is bowed. Is he double jointed?
