Tension destroys wrist cock and takes the naturalness out of it. Seems to me one need not worry about when it happens but rather that it happens at all.
Keeping my hands, wrists, arms, shoulders loose allows me to do what I need to do without wondering about it.
Seems to me if one tries to hinge the wrists, it destroys the tension free motion.
Seems to me also that the shorter the club, the earlier the hinge but who cares; just focus on timing and balance.
