The Vertical Groove Driver is the first radical change to the face of the golf club in decades, yet it couldn't be simpler. Every golf club today uses horizontal grooves; the patented VGG Technology starts by rotating those grooves 90 degrees. Control your slices and hooks with less spin and better dispersion numbers. A smaller head size of 450cc allows less air resistance and faster speed through the ball. The physical properties of this new technology push concentric shock waves away from the shaft giving a crisp, clean response in the hands of the golfer. VGG technology tightens the dispersion and causes a more forward spin and less exaggeration of any slice or hook.
