I have the DVD. VJ does a great job clarifying his point. His demonstrations are excellent and he shows that anyone can learn and perform this simple sequence. VJ is so much fun to watch when he swings and wow, the compression, just awesome.
I don't necessarily agree in using it unless the Hands can dictate the particulars to the pivot so the Hands can take a direct line to the Ball.
I honestly have only tried it with the elbow plane and it was a pivot controlled hands procedure. I haven't worked on it to see if it can be trained to support a Turned Shoulder Plane. But I don't see why it couldn't. But then, I don't know everything.
