Track Kinetic Obsidian Bowling Ball Features:
Track has improved their famous Kinetic series of bowling balls once again. The Kinetic Obsidian uses a Modified Kinetic core, combined with a solid version of the DR-7 coverstock. The combination of the two provides excellent traction in the midlane with an aggressive change of direction at the backend of the lane. This is perfect for medium to heavy oil patterns.
DR-7 Solid: The DR (Delayed Reaction) series of coverstocks are typically used in conjunction with a polished finish. The combination of the two produce great length with a strong reaction at the backend of the lane. For the first time, Track is offering this cover in a solid version with a sanded finish. by doing so, they have created the strong midlane reaction expected from the sanded finish, while enhancing the reaction at the breakpoint due to the inherent chemistry of the DR series.
Modified Kinetic: The Modified Kinetic Core is one of several popular cores in the Track brand. This low RG medium differential and low MB core stores energy longer and responds quicker to friction compared to Track’s other mid performance cores.
