- Balls with the same core
- These balls have the same 15-lb Centrum core as the HALO Vision:
- From the manufacturer
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 in action.
Our latest hybrid creation, better known as eTrax-H19 will only be used on HP4 & HP3 balls. This formulation was created with the help of the chemists at our material supplier in order to produce more surface roughness without losing responsiveness to friction.
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 ball that can be sanded more, or even shined up if so desired. Think Defiant Soul on steroids!
