[O.B.Left]

Im thinking the left wrist is on its way from level to fully uncocked post impact but not getting there until both arms straight. Way past low point. The right wrist at impact is level and shows its impact fix degree of bend (established and frozen by the hitter, or measured at fix and established dynamically during startup by the swinger using a swing back method). The degree of bend at fix is dependent on the shot at hand, ball position, shaft lean etc.

For Horizontal Hinging Im thinking that Both Arms Straight is more literal than for say Vertical or Angled where the right wrist would still show its Fix amount of bend. Clubhead travel being Hinge dependent. As a side bar its this characteristic of Angled Hinging and its associated travel that I think anyways, relates to the "swinging left" craze thats rocking the nation.

As to the right wrist going from level to otherwise. I dont try to do it. That would be a Haneyesque right hand throw would it not?

Are we in the Lab? Hope so, otherwise who are all these guys in white coats surrounding me right now?
