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 of our 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.

Our 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, 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 do the inherent chemistry of the DR series.

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.

The best Track ball of all time?! Absolutely.

I have a few of these, and the only thing I can say is that this is easily the most consistent, predictable and underrated ball I’ve ever thrown. Far bigger than the numbers would indicate, and the ultimate ball for blending a complicated shit out. Now, these things are going for $250+ and even at that, they’re worth every penny. If this ever gets reintroduced, I’ll be the first one in line to buy it. This is a ball that never leaves my bag, regardless of what I’m bowling on or where I’m bowling at. It’s that good.

If you can find one, buy it. Just do. It’s worth it and will very quickly become the best all around ball in your arsenal.
