[Yoda]

Looks like the tripod to me, hopefully in the 7th edition... stationary head, and hula hula.

2-H: "Though the 'Head' Pivot Center is recommended, it is not at all mandatory."

The two sides of the coin are interpereted from this sentence. My side: Homer recommends a stationary head. Another side: Your head doesn't have to sit still. He recommends it for a reason. By the way, a stationary head IS a Basic Essential. But others say the head can sway, and they even promote it. It's what I was taught to do, to no avail. I was even told that this (a sway) creates power. Am I in the ballpark, Yoda??

Close, young Luke. Very close.

Actually, Homer is saying that something at the upper end of the Pivot -- not necessarily the Head -- must remain Stationary to stabilize the motion. He recommended the Head as the Pivot Center because you can tell when it moves (you can see more 'under' the Ball). However, you can alternatively choose to keep the top of the spine -- the point 'between the shoulders' -- stationary. Either way, there is no Sway. In both cases, there is a Centered Pivot Motion. It is all a matter of what the player monitors.
