Brunswick Power Groove Proactive Black Sparkle Bowling Ball
Plastic slips. The Groove grips. And grip is exactly what you need to improve your game. When you’re ready to step up from plastic, get in the Groove.
Want more hook? Move all the way up to Proactive coverstock technology. Compared to Reactive, Proactive coverstock technology increases hooking action in the oil by adding texturizing particles that create a tread-like surface that tractions through heavier amounts of oil, increasing friction and hooking action. Like Reactive coverstocks, Proactive coverstocks can be sanded or shined to create large differences in hook potential. Proactive coverstocks also respond less violently to dry lane surfaces than Reactive coverstocks, creating a smoother, more arcing ball reaction with more control.
Coverstock: The Black Sparkle features Brunswick’s popular Low-Load Proactive coverstock. First used on the Navy Quantum, this Proactive coverstock is the strongest ever used on a Groove class ball.
Core: The Black Sparkle introduces Brunswick’s new DISC (Differential Increasing Side Cylinders) core technology which provides:
The largest track flare potential of any ball in its class
Consistent track flare potentials at all weights from 12-16 pounds
Larger, more consistent pin-out distances at all weights from 12-16 pounds
A more driller friendly design. The precise geometric placement of high density side cylinders maximizes the increase in Track Flare Potential while maintaining perfect dynamic symmetry for easy drilling.
