I believe the desired wrist action is different between golf(double pendulum) and hitting(more smooth lessening of angle between lead forearm and bat as swing proceeds).Has anyone measured this?

Sounds like they are talking about flail only at first with torque between the hands only coming into play at the last moment? In any case, I don't see Bonds hitting with his arms at full extension. No doubt you can hit with the double pendulum action and make contact at full extension with great batspeed (assuming you employ torque and flail all the way through), but I don't think it would result in the high BA Bonds showed to go along with his power. This is just after a quick read of the link but it doesn't sound right to me.
