Best Bowling


Core: The forever famous Centrum Core has now established itself as one of the best asymmetrical cores in Roto Grip history.With its cube type shape and radial disc shape through the middle, continuous motion best describes this core inaction.

Cover: Our latest hybrid creation, better known as eTrax-H19 will only be used on HP4 & HP3 balls. This formulation wascreated with the help of the chemists at our material supplier in order to produce more surface roughness without losing responsiveness to friction.

Condition:Part solid, part pearl and surface texture out of the box means this ball will be cleaner through the front of the lane than the original HALO. Yet it will not be as long down the lane as the HALO Pearl, thus providing a super versatile ballthat can be sanded more, or even shined up if so desired. Think Defiant Soul on steroids.
