- Wrench

First Impressions
The Wrench from Hammer is an absolute prime example of control and perfect readability on the lane. Powered by the proven Wrench Symmetric core, this ball offers very balanced and harmonious core dynamics with a 2.52 RG and a 0.050 differential. Combined with the precisely tuned solid reactive cover, the result is a surface that interacts with the oil in an extremely predictable and consistent way. The 2000 Siaair finish purposefully ensures that the ball picks up friction early and controls the midlane securely, without ever coming across as unpredictable. Even the outward appearance conveys great stability and reliability, qualities that carry over seamlessly into the actual ball motion through the heads. The overall construction is designed to give the bowler clear feedback about the condition of the lane at all times.
Comparison
Looking at the Wrench in direct comparison to the Motiv Venom Shock, its considerably stronger emphasis on control and predictability becomes very clear. The Motiv Venom Shock does offer a somewhat more angular move off the backend, but it can react too sensitively or overreact on difficult oil patterns. This is exactly where the Wrench scores, with its steady, smooth and continuous arc toward the pins. When the Venom Shock tends to miss the breakpoint, the Wrench delivers the traction needed in the pocket to stay safely on course. It closes the gap between extremely strong balls and weaker models absolutely ideally. If you like the Venom Shock 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 get through the boards safely and develops a strong but wonderfully round hook that leads straight into the pocket. The smooth reaction to the friction in the backend produces outstanding carry, since the ball transfers an extreme amount of energy into the pins instead of wasting it prematurely through 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 it should deliver consistently high scores.
