...However, the point I was trying to make is that a rigid spoke/arm attached to a spindle/torso, which is what I thought you were referring to, would not generate anywhere near the speed by rotation of the spindle that our golfing flailis capable of.

Our golfing flail requires no rotary motion to generate, and transfer, its power from top to bottom. This is done by the straightening of the assembly to its in-line condition: arm power in hitting and centripetal force in swinging.

As Homer was fond of reminding us, the golf swing is a body transported - not powered - arm swing.

ah, i think here maybe is the misunderstanding...burner, i (and i think mj) are not saying that hip rotation TOTALLY power the stroke, just that if you use hip rotation to start the whole assembly accelerating (transport) and then ADD the acceleration of the "straightening of the assembly to its in-line condition" you can get higher accelerations than if you just do the later...if (and it can be a big IF imho) you impact the ball in the same manner both ways, the added acceleration will cause the ball to go farther...as a corollary, the more hip acceleration you add, the farther you can hit the ball...however the more hip acceleration you add (imho) the more difficult correct impact becomes and incorrect impact can lose you distance as well...as for throwing, i know baseball players are taught to line up their shoulders down the target line, step toward the target and have the shoulder and arm follow...don't cricket bowlers (correct term?) take steps before they throw?...same idea.
