- X-Calibur Green

First Impressions
The X-Calibur Green from NU Line is an absolute prime example of control and perfect readability on the lane. Driven by the proven Calibur Asymmetric core, this ball offers very balanced and harmonious core dynamics with a 2.49 RG and a 0.055 differential. Combined with the precisely tuned solid reactive cover, the result is a surface that interacts with the oil extremely predictably and consistently. The 2000 Abralon finish deliberately ensures that the ball picks up friction early and safely controls the midlane without ever feeling 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 X-Calibur Green in direct comparison to the Storm Nova, its considerably stronger orientation toward control and predictability becomes very clear. The Storm Nova 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 X-Calibur Green scores, with its steady, smooth and continuous arc toward the pins. Where the Nova tends to miss the breakpoint, the X-Calibur Green delivers the traction needed in the pocket to stay safely on course. It fills the gap between extremely strong balls and weaker models absolutely ideally. For bowlers who like the Nova 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 with too harsh a change of direction. Once the transition sets in, the ball can still be used very effectively with small adjustments to the 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.
