[Yoda]

As a hitter, should the wrists remain completely frozen through impact(like a punch shot) or do they release slightly into the ball, not flip, just decrease the amount of bend and drop the club onto the ball??

Driven by the Uncocking Right Elbow, the Left Wrist Uncocks (Releases) and the Left Hand simultaneously Rolls (maintains its In-Line relationship of the Left Forearm and Clubshaft -- Transfer Power and Rhythm). The Right Wrist remains Frozen in its Level Condition and with its Impact Fix degree of Bend.
