The Tour B330 golf balls feature a firmer TOURcore designed to provide maximum Tour-level distance through increased ball speed. A new cover, the SlipRes, is optimized for maximum spin around the greens, increased friction and spin from the rough and less driver spin for greater distance. A new TOURcore is optimized for performance with swing speed above 105 miles an hour. 330 Dual Dimple Technology offers increased roll, greater distance and more consistent ball flight, and Seamless Cover Technology produces uniform dimple coverage on the entire ball surface. The Tour B330S golf balls also feature the SlipRes cover, optimized for maximum spin around the greens, increased friction and spin from the rough, and less driver for spin for greater distance.
