Brunswick Power Groove Reactive Pink/Blue Pearl

Features Coverstock: All Power Groove Reactive balls feature a factory polished version of Brunswick(r)'s popular PowrKoil 17 Reactive coverstock. Factory polishing helpes create a more skid/snap reaction that saves most of its hooking action for the back part of the lane. PowrKoil 17 is the strongest Reactive coverstock ever used on a Groove class ball. Core: The Power Groove Reactive group feature Brunswick(r)'s 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; and 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 dynamic symmetry for easy drilling.
