Actually Tommy's GI interview describes the up and down motion of the right forearm perfectly as Homer describes it per section 7-3. I believe the drill you're talking about (the 10 step sequence drill), that first move, the one to two position is to show/demonstrate the right wrist (only) bends and the left wrist turns and cocks. However, during actual play, if you are going to use the right forearm takeaway, its a folding up of the right forearm from the address position....it's a very precise movement. Not surprised you were crushing the ball. It's a great feeling not to guess where the club is going in the backswing. It's "The Magic of the Right Forearm"...that it is....

The sad part is that I spent 5 years doing it wrong. Oh well... Time to view my old 'Knowledge' vid to see what else I got wrong.
