The New Yonex VMX woods come equipped with a Yonex-engineered HS600 Carbon Graphite shaft that incorporates Hi-Stability technology for improved accuracy and the Centrifugal Force System (CFS) for increased clubhead speed and greater distance. New for 2009, the VMX driver and fairway wood series feature the new V-Slot technology which provides a lower and deeper center of gravity for increased distance and unmatched forgiveness. The Aero Pentagon Shape enhances distance and power by reducing air resistance around the head for greater stability and clubhead speed throughout the swing. The tungsten weight in the heel further lowers and deepens the center of gravity while helping to square the face at impact.
