Mystify your opponents with the Roto Grip Exotic Gem!

The Gem line has a new rock for your collection - Exotic Gem. This strikingly beautiful ball features MicroTrax Pearl reactive coverstock, finished with ReactaGloss. This cover formulation paired with the polished finish will provide extreme length and backend power on medium-heavy lane conditions.

Inside, the Defiant LRG asymmetric core rev up early and retain energy to unleash on the pin deck. 
Here's what Roto Grip has to say about Exotic Gem:
Striking. Alluring. Captivating. Call it what you will, but we prefer to call this enchanting and outstanding performing ball what it truly is, EXOTIC! From its ravishingly good looks to its dominance on those Medium/Heavy oil conditions thanks to the combination of the Defiant LRG Core (our fastest revving asymmetrical core) & MicroTrax Pearl Coverstock (our earliest and most aggressive pearl cover we currently offer on any ball), everyone will take notice when you hypnotize them with the Exotic GEM™.


The Duo is a very good option for medium oil conditions that offers plenty of versatility for bowlers of all different styles. It takes well to surface changes to further increase the ways it can be used.


While the Duo was at its best on our medium oil pattern, we didn't have quite as much forgiveness on the heavy oil and dry conditions. The ball took well to surface changes to combat the fresh, while the box finish was in play once the patterns started to go through their transition.

Overall Summary

The Duo uses the MicroTrax Pearl cover from the Exotic Gem and the new Mentor symmetrical core design. This ball is a very good option for easy length and a strong move at the breakpoint and back end.
