Precision is key for successful bowling! Track knows this so they created the Track Precision Solid bowling ball. This ball uses the Prime Solid coverstock which offers a consistent grip on the lane gives this ball the ability to dig hard at the mid lane without using up all of its energy. This ball uses the single density version of the Precision SD core. This uses a low RG, high differential and large mass bias to achieve the desired reaction. The Track Precision Solid was designed provide great traction at the mid lane area as well as motion down lane when up against heavy oil conditions.
