Constructed using 10% carbon-fiber material, the Graf Supra G15 Grip Composite Stick features D3 flex zones, a thin foam-core blade, and an enhanced grip for ultimate performance. The D3 flex zones consist of a top-zone flex, mid-zone flex, and taper-zone flex. The flex zones enhance flex differential between blade and handle of the shaft for an improved kick. Higher-modulus graphite in the taper zone adds a third rate of flex for a faster response. The thin foam-core blade creates livelier shots and better trajectory.
