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. (1-L-1&2) 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 great one??
