Faster and longer than the original RocketBallz driver, the TaylorMade RocketBallz Stage 2 Driver comes with a thick-thin crown that provides a lower and more-forward center of gravity location, thus promoting a faster ball speed, higher launch, and lower spin. Inverted Cone technology milled into the inner side of the larger clubface expands the portion of the face that delivers high ball speed. The expansive 4,100 square-millimeter clubface gives the golfer substantially more face area, and improved aerodynamics reduces drag over the head to promote faster clubhead speed.
