Drew told the story behind...but I really don't know is that pivot to hand or hand to pivot....Mr. Ben Doyle said in his DVD "The Hands are controlling the pivot, the hands are...come on pivot, take me back, assemble, load me, come on delivery me and releasing through the ball..."
I have a question long in my mind: Can we both monitor the hands and pivot at the same time?
