Overview
A bowler who wants more versatility across oil patterns is the target of this Roto Grip ball. It pairs the NanoStar coverstock with the ROCKER Core, a weight block shape meant to give a more centralized rotation plane.
The reason to look at this ball is the coverstock's position between earlier and cleaner-reacting Roto Grip materials, which broadens the conditions it can handle. The limitation is its focus on medium to heavy oil, and no drilling detail.
Who it's for
Competitive and advanced players who see varied oil patterns and surfaces will use the coverstock range. Beginners, and bowlers who need a drilled ball or entry-level reaction, should choose something else.
Pros and cons
- Versatile across oil conditions
- Centralized rotation from the core
- One year limited warranty
- Aimed at advanced players
- Drilling not stated
- RG and differential not listed
Performance notes
The NanoStar surface grips mid-lane similarly to MicroTrax but does not dig in as early, and it responds more to friction down lane. The ROCKER Core shape moves the rotation plane toward the center, which supports continuation through the pin deck.
