The new Tour B330-RX boasts a 7% softer core with a reformulated mantle that further reduces excess spin, resulting in straighter, more precise shots. With its Very SOFT gradational compression core, the ball is even more easily compressed for longer distance and great feel. The new core combined with B330-RXs new Ionomer Inner Cover provides an increase in velocity and reduction in sidespin with the driver and long irons. As was the case with its award winning predecessor, the new B330-RX not only offers unparalleled distance performance, but the 330 Seamless Dimple-design urethane cover also ensures Tour caliber greenside spin and control, with a consistent trajectory players can count on.
