From the manufacturer

The now famous Centrum Core has quickly become a fan favorite due to the radial disc which helps increase rotation/continuation for all styles of players. This core is driller and bowler friendly which means no matter how you drill it or how you throw it, it always gets rolling.

This cover was first introduced on the IDOL Pearl. It is the newest pearl formulation that will be used on HP4 & HP3 balls moving forward. This cover provides a good footprint in oil while still maintaining a strong responsive reaction to friction.

This ball was designed to be the perfect complement to the original HALO. Sure, both balls feature the same core. However, the big difference is the coverstocks. Wrapping this core with the eTrax Pearl cover creates motion in a completely different part of the lane. If you were to drill a HALO Pearl and a HALO the exact same, you would see approximately 6-8 feet more skid, which transcends into A LOT MORE BACKEND!
