Bridgestone Golf has made significant improvements to it’s B330 line of golf balls. The most heralded improvement is the SlipRes cover that took the leading rubber manufacturer four years to perfect. The cover is supposed to produce less driver spin and increase compression for more length off the tee, more spin from the rough and around the greens and more durability. Bridgestone claims that this ball “repairs itself”, making it the longest lasting ball the company has ever produced.
