The Track Alias high performance bowling ball was designed with all bowling styles and all lane patterns considered. This ball can be drilled for any circumstance you might find yourself facing. This ball can be transformed for a smooth, strong mid lane delivery or an angular motion. This is all achieved due to the versatile Alias core that is being introduced with this ball. Track designed this core to have an extremely tight pin distance and top weight spec. This will allow the driller to accomplish multiple mass bias drilling angles without the need of a weight hole. This also creates an intermediate differential range of perfectly symmetric .000 Intermediate Differential to a very asymmetric, high Intermediate Differential. This unique core is covered with a Prime Hybrid coverstock and is finished with a 500/2000 sanding. This cover responds quickly to friction on those heavier oiled lane conditions and provides a lot of hook.
