which one is better?
Depends if you like to play from the right or the left side of the course.
This is how I feel. If my arms are outracing me in the backswing, my hands and arm gets really really behind me, and I'm having a tough time hitting the ball, mostly fades or slice sometimes. Maybe it's just how i feel.
I have the exact same problem, although both of us suffer from underplane issues anyways.
I think now that we should be focusing on the CP and flick release, allowing the arms to out race the body is probably not the ideal way to start the swing. Personally I have a hard time moving my hands away from the target on the DS when I don't get a full turn in the backswing. And the only way for me to get a full turn is if my arms don't out race the body.
BUT BUT, I WANT TO SHAPE THE BALL! HAJust hit the damn ball!
Just hit the damn ball!
The most foolproof method is to use the displacement of your body weight to give momentum to the power package. You must, however, resist any movement of the first or second lever with relation to it's higher part until the momentum gains and overcomes it.
