You're all over it . . . Standard Knee Action - "This sequence produces maximum Hip slant at each end of the Stroke."

Now for the WHY?

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??
