Groove Dynamic Reactive Blackberry Sparkle

Brunswick’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
• 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 symmetry for easy drilling.
