Is there a way of determining the amount of hookface in a club. Is it related to forward shaft lean, and if so, is there a formula-type relationship?
The shorter the Club, the more hooked the Face. That's because the shorter the Club, the sooner it gets 'in line' after Release and the greater the amount of hook-face necessary to divert the Ball from its true tangential path -- at right angles to the Swing Radius -- to the Target Line.
