How often do you stop by the LBG Gallery and look at the Yoda-Hogan side by side pictures? Hula Hula with a very powerful right shoulder driving down to the ball. The left shoulder, just as Mr. Kelley says, just reacts to the right shoulder. I think some of us spin that left shoulder out to early. Accumulator #4 is released by the right shoulder- the right shoulder thrust. Leave the left shoulder alone so it can be the fulcrum and hinge pin.
Nice pics, almost as good as a side by side picture of Liv Tyler and Kiera Knightley.
