Overview

Pushing its familiar core shape to the highest RG and differential yet, Roto Grip made the Gremlin roll long and then turn with continuous motion. The mild asymmetric shape behaves like a symmetric ball with a balance hole.

Length and continuation suit bowlers who want angle without an abrupt hook on heavier oil. The listed weight is light, and exact core numbers are not given.

Who it's for

Advanced league and tournament bowlers on medium to heavy patterns suit this ball. Beginners should start with a more forgiving reactive.

Pros and cons

Pros
  • Long, continuous motion
  • Pearl cover for length
  • Mild asymmetric versatility
Cons
  • Core numbers not listed
  • Too strong for dry lanes
  • Drilling not mentioned

Performance notes

Higher RG delays rev up for length, and higher differential adds flare for a strong turn. The pearl cover clears the front before it grips. Layout choice changes how sharply it moves.
