I've been working with TGM thoughts and materials for approximately 5 years. I give Lynn, Ted, and others all the credit in the world for teaching me the flat left wrist and hitting concepts that drove me down to around a 5-6 handicap. However, I've never had that magical par round yet. I always had a problem with the occasional flip, which led to a leakage hook and the double bogey hole. Recently it finally dawned on me(I'm a bit slow) that when I slid my right heel(right handed) toward the ball to initiate the downswing, I no longer lost the bend in my right wrist. This improved footwork has dramatically improved my consistentcy, by getting my closer to the ball and allowing me to not run out of right arm.
This was an area I had never really focused on and for any of you out there still flipping, I would recommend reviewing this part of your swing.
