Roto Grip created the Halo bowling ball to dominate heavy oil conditions. This ball introduces the Centrum asymmetric super strong core and pairs it with the proven and strong MicroTrax-S18 coverstock. This pairing produces the same type of motion found with the Hyper Cell and No Rules but takes it up a level in strongness!

MicroTrax-S18 Coverstock
Type
Solid Reactive
In testing and development we stumbled upon our strongest blend of Nano technology for the Roto Grip Brand to date, MicroTrax-S18. With tweaks in formulas and mix ratios we have created a coverstock that provides even more traction and is overall more aggressive than the Micro DNA Coverstock.
Centrum Core
It took more than a year to develop this unique-shaped core, which increases its rotation/continuation once the ball is in motion.
