One of the most popular shafts on the JPGA Tour is the Graphite Design Quattrotech MD 8 Wood Shaft. This shaft is a variation of the very successful Quattrotech shaft. The use of four-axis material makes this shaft the highest performance golf shaft today. The qualities are exceptional feel and control, and this design has the four-axis material in the tip, generating a Tour-trajectory ball flight with optimum spin for the better player.
