Roto Grip Wicked Gremlin Review: Heavy-Oil Traction With Controlled Continuation
The Roto Grip Wicked Gremlin brings the powerful Rondure MaxD asymmetric core back in a stronger, more controlled package. Its new G-R1 Solid Reactive coverstock is built to create dependable midlane traction on medium-heavy oil while maintaining a smooth, continuous move through the pins.
At A Glance
The 15-pound Wicked Gremlin has a 2.50 RG, 0.058 differential, and 0.010 PSA. Those numbers indicate an asymmetrical ball with high flare potential and strong overall traction, but its relatively modest PSA helps it create a more continuous and controlled shape than an ultra-aggressive heavy-oil asymmetric.
The Gremlin Core Returns
At the center of the Wicked Gremlin is the Rondure MaxD core, the same asymmetric shape used in the original Gremlin. Roto Grip designed the core with a precision-tuned density profile, producing an energetic motion that creates length through the fronts before transitioning into a powerful and continuous backend reaction.
Within the Gremlin family, the Rondure MaxD core has the highest RG and differential. This pairing gives bowlers strong flare potential and a powerful engine while retaining usable length through the front part of the lane.
That core design also supports one of the Wicked Gremlin’s key benefits: forgiveness. Roto Grip positions it as a ball that gives bowlers more room for error, helping shots that are close to the intended target line maintain enough continuation to carry more consistently.
New G-R1 Solid Coverstock
The major change from the original Gremlin is the coverstock. The original Gremlin used the V-R1 Pearl Reactive cover, which was designed for cleaner length and a sharper, more angular backend motion. The Wicked Gremlin replaces it with the new G-R1, or Grip-Response, Solid Reactive coverstock.
G-R1 is a nano-free solid formulation created to provide a tackier, more stable footprint in the oil. Instead of producing the abrupt response often associated with aggressive solid covers, it is intended to create strong midlane traction, a smoother transition, and a predictable continuation through the pins.
The 2000-grit Abralon factory finish reinforces that motion. It gives the Wicked Gremlin enough surface to read medium-heavy oil without making it so early or slow that it burns up before reaching the pocket.
Expected Lane Reaction
The Wicked Gremlin should be a strong choice when bowlers need more traction than a cleaner hybrid or pearl can provide, but do not want the early hook or abrupt response of their strongest asymmetric solid. Roto Grip describes it as a “step-down” option when aggressive asymmetrics begin hooking too soon.
Bowlers should expect:
- Strong and stable midlane traction.
- High flare that helps the ball create motion in heavier oil.
- More control and smoother transition than the original pearl Gremlin.
- Continuous backend motion instead of a sudden skid-flip response.
- Strong drive through the pins when there is enough oil to support the solid cover.
- Useful forgiveness when a shot misses slightly inside or outside the intended line.
This makes the Wicked Gremlin particularly appealing on fresh house shots with volume, medium-heavy sport patterns, and tournament transitions where players need to blend the lane rather than chase extreme angularity.
Who Should Consider It?
The Wicked Gremlin is a strong option for:
- Bowlers needing a controllable asymmetric solid for medium-heavy oil.
- League players facing fresh patterns with tighter fronts or more volume.
- Tournament competitors who need a strong ball that blends wet/dry transitions.
- Bowlers who loved the original Gremlin core but want more midlane traction and a smoother shape.
- Players whose strongest asymmetric solid starts too early or loses energy before the pocket.
Speed-dominant bowlers who need help creating traction without relying on an extremely early, high-PSA core design.
For rev-dominant players, the Wicked Gremlin can fit when the lane has enough oil to support its 2000-grit solid cover. For speed-dominant players, the high-flare core and traction-focused shell can provide an earlier, more dependable read than cleaner equipment.
Layout And Surface Considerations
The factory 2000-grit Abralon finish is intended to balance traction and continuation, so it should be tested as delivered before making adjustments. It is especially suited to medium-heavy conditions where the ball needs to read the lane but still retain energy through the pin deck.
A benchmark asymmetric layout can highlight the Wicked Gremlin’s smooth, continuous motion and lane-blending ability. Players looking for more downlane response can use a layout that delays the transition slightly, although the G-R1 Solid cover will still favor control and traction over a sharp skid-flip reaction.
If the Wicked Gremlin reads too early on lower-volume conditions, a pro shop can raise the surface to create more length. If it begins to push too far on heavier or longer oil patterns, refreshing the 2000-grit finish can restore its intended midlane traction.
Final Thoughts
The Roto Grip Wicked Gremlin is not just a solid-covered version of the original. It preserves the Rondure MaxD core’s high-flare potential and forgiveness, then pairs it with a new traction-focused cover designed for smoother and more predictable heavy-oil performance.
For SpareTime Bowling readers, the Wicked Gremlin is best described as a controlled medium-heavy oil asymmetric: strong enough to handle fresh volume, smooth enough to blend difficult lane conditions, and continuous enough to keep driving through the pins.
