Lynn and Jeff, the problem that I see is that if we want to start the takeaway with the rear forearm in line with the shaft is that:
- either the arm is too bent in elbow and the ball position too much forward without any cock of the wrist at address
- or one needs to execute an impact fix position at address with a relatively strong RH grip.
I believe that is why e.g. Hogan was perfectly aware that both are unefficient methods of addresing (vide: "5 Lessons") and he accepted the fact that the rear forearm magic start to act exactly when the golfer returns to the elbow plane during downswing - the sooner the better.
