We’ve re-engineered the core by increasing its density, effectively lowering the RG for an earlier mid-lane read and boosting the Differential for enhanced track flare. This internal evolution ensures the ball revs up faster and delivers a more aggressive, continuous motion through the pins. To match this updated core, the hyped UP!™ features the V-R1™ Hybrid Reactive coverstock. This advanced hybrid shell provides the perfect balance of "clean and mean," effortlessly clearing the front of the lane while maintaining a strong, predictable response to friction. It offers the versatility to handle various medium oil patterns, blending the smoothness of a solid with the explosive backend of a pearl. The result is a versatile powerhouse that honors its heritage while delivering the extra punch today’s bowlers demand. Whether you are attacking a fresh house shot or navigating a transitioning lane, the hyped UP!™ provides the perfect step up from the Hustle™ Series or a step down from your higher end balls.
