The PXG 0811 driver,which features sixteen moveable weights and an adjustable hosel,offers players fine-tuning options never before seen. The various combinations enable the golfer to hone their launch conditions for optimal ball flight while retaining a high MOI (moment of inertia). Research has proven that fine-tuning head weight and swing weight is a very important,yet highly underutilized,fitting attribute to optimize performance. PXG prohibits online sales. Please see either D'Lance Golf Performance Center or Touchet Performance Golf to get fit!
