Factory Finish
Reacta Gloss
MicroTrax Pearl Coverstock
Type
Pearl Reactive

Bottom line, this coverstock technology just flat out crushes in terms of performance. Featuring a 100% nanoparticle load, this pearlized concoction provides midlane traction and response to friction while maintaining its surface profile over a longer period of time to ensure you get maximum performance each and every time. And just like the solid version, the pearl version displaces oil at the highest rate of any of our pearl covers. Basically, think of it as added forgiveness on those not-so-great shots off your hand.

Mentor Core
Roto Grip Mentor Core

Dynamic power to the core, the symmetrical Mentor™ Core was built to produce plenty of positive motion. From its mushroom/bulb shape structure to the heavy density flip puck on bottom, (to give it extra giddy up) this part was constructed to deliver added forgiveness in the back part of the midlane and down lane where you need and want it most. To be perfectly honest, this latest addition to the HP3 family of cores was erected and developed from the inspiration of the Madcap™ Core numbers (DareDevil™ Series) from yesteryear. It’s ok, you can thank us later.
