***It would be difficult to justify a hinge since the shaft is held in the
hands over 5 to 7 inches of length and the wrists are not flopping around
during the down swing. The wrists are generally releasing under muscular
control during the down swing. If we were holding the club in one hand the
hinge model may be appropriate but in two hand we have more leverage and
muscular control.
For the rigid body motion of the club, you are correct. But for the
oscillatory motion, where the displacements are small, particularly the
part of the shaft in the hands, I stand by the hinge being a better model
than a cantilever or free end.
