Hammer wants you to make a statement with the Hammer Statement Pearl High Performance Bowling Ball. This ball uses the very responsive Aggression Pearl CFI coverstock which is finished with a 500/1000 grit and then polished. The coverstock offers good length through the front of the lane and an aggressive backend reaction. The Statement core in this ball has a very low RG with a high differential as well as a strong asymmetric core. This core design helps the ball rev up in heavy oil conditions. The design of this core places the majority of the mass at the bottom of the core which assists in storing energy. This bowling ball is Carbon Fiber Infused! Carbon fiber is one of the toughest materials on earth. Hammer decided to add this material to the inner core of this ball for added strength and durability allowing them to offer an incredible 3 year warranty.
