718A

Coverstock: Outer shell of the ball; UMP Gen 4A Reactive™ Pearl
Finish: Surface texture on the ball (sanded, polished, etc); 800, 1000, 2000, 2000 Abralon® sanded, polished with Powerhouse Factory Finish
Lane Condition: Length and/or amount of oil on the lane; Medium/Medium-Heavy
Color: Color of the ball; Black/Blue/Caramel

Core: Weight block inside the ball; Robot
Core Type: Basic shape type of the core (Symmetric, Asymmetrical, Pancake); Asymmetrical
RG: Radius of Gyration: measurement related to weight distribution of the core. This affects how quickly a ball will get in to a roll. A ball with a higher RG will roll later. A ball with lower RG will roll sooner.; 14 LB. - 2.48; 15 LB. - 2.50; 16 LB. - 2.51
Differential: Difference between the RG of the core's x-axis and y-axis. Indicates track flare potential and stability. A higher differential means more flare potential and less stabilty. A low differential ball will be more stable and have less flare potential.; 14 LB. - .054; 15 LB. - .058; 16 LB. - .055
Intermediate Differential: Difference between the RG of the core's x-axis and Z-axis on an asymmetrical core. Indicates the asymmetry of the core. A higher intermediate differential ball will be less stable and will transition more quickly from skid to roll than a ball with lower intermediate differential.; .018

Description: This all new 7 Series ball, the 718A, was designed to be a new and improved version of 2009’s 715A. In the two years since the introduction of the 715A, we have been working to design a more usable product for the masses. We used your feedback to design the 718A.
