My classically shaped drivers featuring a graphite composite crown allow me to move 12 to 14 grams into the rear apex. Two strategically positioned weight screws, of 2 (gold) and 12 (silver) grams expand the Triangle of Stability™, maximizing the accuracy-enhancing phenomenon known as the “gear effect.” Using a rare Russian BT-23 beta titanium face for maximum compression and feel, its hardness and strength reduces spin and increases ball velocity.
