0.5IN ABOVE CENTRE

The vertical roll on your driver makes the higher part of the face more lofted; strike from here and you get a free launch boost, helping carry. A high strike also moderates backspin by triggering vertical gear effect, a phenomenon that sees the ball want to spin in the opposite direction to the way the face deflects. Half-an-inch above centre removes around 450rpm of spin. Some studies also suggest that as the toe moves faster than the heel in a rotating face, a strike slightly into the toe also helps distance.
