The shoulders are dual agents. They are part of the pivot and part of the power package and refered to as Accumulator #4. Shoulder action (as initiated by the hips) is the start down acceleration for the swinger and it loads the #4 pressure point which is where the inside of the left arm presses against the chest. The right shoulder ideally travels down the same plane as the hands. Once the hands are "at speed" the swinger simply keeps the hands ahead of the clubhead into and through impact.
