Product Description
Available now for PBA players andComing soon for all, the Black Pearl Urethane Hammer features the same great urethane cover formulation and LED core as the legendary Purple Pearl Urehane Hammer, but updated to a 78D hardness to comply with new PBA competion rules. The cover on the Black Pearl Urethane Hammer is prepared with a 500 grit Siaair Micro Pad and will be duller out of the box as compared to the Purple Pearl Urethane, which came at 2000 Grit Siaair. This duller finish helps bridge the gap in reaction that can be expected due to the harder surface. You will find the cover will still dig in early on the lane and provide the ultimate in control down the lane.
