golfbulldog i understand where your coming from and agree with what you say is going on. However my FEEL is obviously very different to yours. If i think about the pivot slowing down i'll quit and have throw away.
When i practice hitting balls left handed i concentrate on throwing the left arm off the chest. I know as you say for this to happen there must be some slow down of the pivot, but to me it still feels like theres so much work going on there. The pivot certainly doesn't give up the ghost after accumulator #4 is released. For me trying to slow down the pivot is a terrible swing thought, far better to think about throwing a heavy left arm at the ball and let your body respond naturally.
