- Black Mamba

First Impressions
The Black Mamba from AMF is an absolute prime example of control and perfect readability on the lane. Driven by the proven Mamba core, this ball offers very balanced and harmonious core dynamics with a 2.51 RG and a 0.048 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 1000-grit pad finish purposefully ensures that the ball picks up friction early and controls the midlane securely, without ever feeling unpredictable. Even its 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 Black Mamba directly against the Storm Phaze II, its much stronger emphasis on control and predictability becomes very clear. The Storm Phaze II 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 Black Mamba scores, with its steady, smooth and continuous arc toward the pins. Where the Phaze II tends to miss the breakpoint, the Black Mamba supplies the traction in the pocket needed to stay safely on course. It closes the gap between extremely strong balls and weaker models absolutely ideally. If you like the Phaze II 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 cover boards confidently 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 sharp 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.
