Most golf shafts maintain a similar flex profle throughout various flexes. In this scenario, a lower launching shaft, suitable for a scratch golfer, may be less than ideal for a golfer with a slower swing. Our patented DFP remedies this dilemma. As the overall stiffness of the shaft increases, its tip section stiffens and its resistance to torque increases to generate a more boring ball flight. From the illustration below, you can see one aspect of the DFP design. The tip and first taper sections of the R flex shaft are lengthened to give it a higher launch angle as compared to the S flex shaft.
