The Wilson Staff Tx4 is for tour players and discerning amateurs who demand the ultimate in workability, the 4-layer Tx4 fits the bill. With a PhD advanced dimple design, a Nano Tech core, and a Fusion layer, all systematically wrapped in a spin-inducing Urethane Elastomer cover, the Tx4 performs so accurately, pins don't stand a chance. The PhD advanced dimple design has 312 flat-bottomed, shallow dimples (Pan Head) to rip through the air to create a more stable, high trajectory flight. The Nano-Tech core has Nano particles infused into the rubber chemistry produce an extremely lively but soft inner core. The Fusion Performance mantle layer fuels maximum acceleration off the club face and generates higher spin rates. The Urethane Elastomer cover promotes spin, delivers soft, scuff-resistant performance and provides extra control on scoring shots.
