Maria Sharapova and Tomas Berdych have made Head Instinct their racquets of choice, and the new Graphene Instinct MP will make them even more powerful in 2013. The Instinct fits the modern game very well: it’s not too heavy, is stiff enough to be powerful but not harsh, and the 100 square inch head size is perfect for “new school” topspin. Head has improved the Instinct MP for 2013 with the inclusion of graphene. By using graphene – the world’s lightest and strongest material – in the racquet shaft, Head has been able to move weight from the shaft to the tip and handle, increasing power and stability without changing overall racquet mass (more weight in the head provides greater plow through from the baseline, and more mass in the handle reduces torque and recoil). With the addition of graphene, the Instinct packs extra power with less effort, and is more maneuverable, a combination modern games can’t help but succeed with. YouTek technology’s “cross-linking” abilities stabilize the frame on faster swings and create more feel on touch shots. Strong baseline and all-court players should put the Head Graphene Instinct MP at the top of their demo list.
