Roto Grip Cage Bowling Ball Core
When needing midlane motion the Cage™ Core is exactly what the doctor ordered. With its top and bottom caps sandwiched around the ribs of the core body, this core creates motion like nothing else on the market.
The Cage Core, first featured on the Sinister features medium-RG/High Differential/High MB Differential that reads the mid-lane and reacts with a phenomenal motion on the back end. Heads will roll with this kind of motion, making it perfect for the heaviest of oil patterns.
