Yoda - yes. I definitely meant that the hands lead the pivot when I refer to a reactive pivot swing action.
I know that you strongly believe that the pivot must be the source of the energy/force that secondarily causes the arms to move in a circular motion and that the pivot represents the central torque generator which causes the kinetic sequence to operate in a set sequence - first lower body, then upper body and then the arms (like a figure skater spinning on the ice).
That's an active pivot swing, which is the best choice for flexible golfers.
However, I still believe that the reactive pivot swing is a viable option for elderly inflexible golfers. Jim Hardy uses the reactive pivot model in his Hardy 2PS model and Leslie King also uses this reactive pivot model in his arm swing model. It has many disadvantages, but it also has many advantages for golfers who cannot pivot correctly due to biomechanical limitations.
