- Groove Urethane

First Impressions
The Groove Urethane from Brunswick is an absolute prime example of control and perfect readability on the lane. Powered by the proven Groove Core, this ball offers very balanced and harmonious core dynamics with a 2.58 RG and a 0.020 differential. Combined with the precisely tuned urethane cover, the result is a surface that interacts with the oil in an extremely predictable and consistent way. The 1000 Siaair finish deliberately ensures that the ball picks up friction early and controls the midlane securely, without ever coming across as unpredictable. Even its outward appearance conveys great stability and reliability, qualities that carry over seamlessly into its actual motion through the heads. The whole construction is designed to give the bowler clear feedback about the condition of the lane at all times.
Comparison
Looking at the Groove Urethane in direct comparison to the Storm Pitch Black, its much stronger orientation toward control and predictability becomes very clear. The Storm Pitch Black does offer a somewhat more angular move off the backend, but on difficult oil patterns it can react too sensitively or overreact. This is exactly where the Groove Urethane scores, with its steady, smooth and continuous arc toward the pins. Where the Pitch Black tends to miss the breakpoint, the Groove Urethane provides the traction in the pocket needed to stay safely on line. It closes the gap between extremely strong balls and weaker models absolutely ideally. For bowlers who like the Pitch Black but are looking for a calmer, safer option, this is the logical choice.
On the Lanes
On the lane this ball proves to be the perfect companion for medium to heavy oil patterns, especially on typical house shots or demanding sport patterns. It lets you move through the boards with confidence and develops a strong but wonderfully round hook that leads straight into the pocket. The smooth reaction to the friction on the backend produces outstanding carry, since the ball transfers a great deal of energy into the pins instead of wasting it prematurely on an overly hard change of direction. Once the transition sets in, the ball can still be used very effectively with small adjustments to your line before a ball change becomes necessary. It is a true benchmark for anyone who wants to build their game methodically and should deliver consistently high scores.
