Kinetic Obsidian

We've improved our famous Kinetic series of bowling balls once again. The Kinetic Obsidian uses our Modified Kinetic core, combined with a solid version

DR-7 Solid:Our DR (Delayed Reaction) series of coverstocks are typically used in conjunction with a polished finish. The combincation of the two produce great length with a strong reaction at the backend of the lane. For the first time, we are offering this cover in a solid version with a sanded finish. by doing so, we 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 propular 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.
