Performance Analysis

Performance Analysis

The Roto Grip Gremlin is scary good — and the numbers prove it. With 1,085 units sold shortly after launch, this ball has become an immediate hit. The Rondure asymmetric core boasts a .058 differential, making it the strongest asymmetric core in Roto Grip’s current lineup. Paired with the V-R1 Pearl Reactive coverstock and Storm Power Edge finish, the Gremlin creates one of the most explosive pearl asymmetric motions available.

The combination of pearl coverstock on an aggressive asymmetric core creates a unique motion: clean through the front with a violent, angular backend reaction. On transition — when the fronts are burned up and the backends are still holding — the Gremlin shines. It pushes through the dried-up heads and still has enough energy to make an aggressive move at the breakpoint.

Who Is This Ball For?

The Gremlin is built for power players and tournament bowlers who need an angular weapon for transition. If you throw it with speed and revs, the Rondure core will reward you with massive entry angle and devastating pin action. Anthony Simonsen’s endorsement speaks volumes — this is a ball designed for bowlers who want to create separation on the backend when conditions break down.

The Gremlin’s modified core simply is amazing. I was able to try this ball on the fresh and the burn and it gave me a great look. The ball on the fresh, I was able to play a little further right around 7-8 board at the arrows. The ball definitely started picking up a touch sooner than I expected but the lanes this summer have been playing with a bit more friction than last summer. Now I was able to jump back on the same lanes at the end of the night after the league and I was blown away with the versatility of this ball. My first handful of shots I was rolling the ball around 15 at the arrows out to about 5 and the ball just ripped off the spot and continued through the pins. Moving a little more left I tried to throw around 20 at the arrows to keep it a little tighter and a handful of shots I missed in gave me some good mix strikes. But the ones that seemed to get to the 12-14 board area on the lane came back high flush.
