Not really sure where to post this as there is no right arm swing emergency room (although that'd be nice!).
DG or Coophitter - do you consider maintenance of the flex in the trail kneee a big part of Tom's method? I've been struggling with pulls a bit recently, and have been thinking its either from cocking the right wrist, going out at the ball ('OUT AT THE BALL!') before I go down, or (most likely) an overactive body. Today, after some experimentation, I found a focus on right knee flex really helped me slow my body rotation and stay on my right side longer in the downswing - also good extension in follow through - straighter shots and better contact.
My tendency has always to get a bit standard knee actionish - a straigtening right knee in the backswing. Is a focus on more of an anchored right knee a good way to go for a Tomasello style swing?
