Have only recently come across the subject of hitting up on the ball with the driver (ala Bubba Watson, JB Holmes and many others). Makes sense to me, with one exception ...
In order to maximize power, I have been taught to keep my hands ahead of the ball at impact (causing the shaft to be slanted). Isn't this in contradiction with hitting up on the ball? I can only visualize the club rising much later in the release stage!
Is this where the spine/ axis tilt comes in handy? ... would love for someone to elaborate on this aspect of swing mechanics.
