- Challenge

First Impressions
The Challenge from Ebonite is an absolute prime example of control and clean readability on the lane. Driven by the proven TRM core, this ball offers very balanced and harmonious core dynamics with a 2.50 RG and a 0.048 differential. Combined with the precisely tuned Traction Solid cover, the result is a surface that interacts with the oil in an extremely predictable and consistent way. The 2000 Abralon 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 Challenge in direct comparison to the Storm IQ Tour, its considerably stronger focus on control and predictability becomes very clear. The Storm IQ Tour 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 Challenge scores, with its steady, smooth, and continuous arc toward the pins. Where the IQ Tour tends to miss the breakpoint, the Challenge 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. For bowlers who like the IQ Tour but are looking for a calmer and 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 securely 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 through too harsh a 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.
