Thanks Justin. The Hogan Book is an excellent read. I have the book and recomend it to any seriuos student of the game. Unfortunately, the first few chapters did not print in your attachment. They have quite a bit of Homer Kelley in them: "the human body in motion is a mechanic apparatus" and Hogan's explanation of Hand Control Pivot hits the nail on the head, "what you intend to do with the hands dictates where and how the arms move".
