 
Designed with every bowling style in mind, the NEW Alias core is the most versatile core that Track has ever created. Because of the extremely tight pin distance and top weight spec we have enforced, it will allow the ball driller to achieve multiple mass bias drilling angles without the addition of a weight hole. This also will allow for an intermediate differential range of perfectly symmetric .000 Intermediate Differential to a very asymmetric, high Intermediate Differential.
