Bowlingball - Roto Grip - Gremlin

Your new favorite pearlized ball has been hatched to help advance your game in ways you didn’t know you needed. Now some will say, “hey, I’ve seen that core shape before” and to those we say, “yes, yes you have.” BUT what we can also say is that you have never seen this MAXED-OUT version of this core shape before known as Rondure™ MaxD. That’s right, our team of mad scientists in the R&D Lab pushed this core shape to its limits by changing the densities of both the block and the slug on bottom to create the highest RG value and highest Differential value this part has ever seen. From its inception, this mild asymmetric shape was created to emulate the motion of a symmetric core shape with a balance hole in it. Fast forward to this newest version, and well, even though previous models were fantastic, this version is without a doubt the longest and most continuous down lane that we have ever seen.

But it doesn’t stop there, the mad scientists in the R&D Lab also managed to formulate a brand-new nano-free coverstock material during this development and testing process as well. That’s right, the versatile response (V-R1) cover formulation was created to handle a wide range of oil conditions and oil types. From the fresh, to the transition, to the burn, this cover provides easy push through the front of the lane while consistently responding to friction down lane without getting out of control.

So, if you are in the market for a pearlized ball that complements your big strong asymmetrical balls, or if you are needing a pearlized ball that allows you to move deeper on the lane and still comes around the corner, then you must add one of these to your bag. But you don’t have to take our word for it. Try it for yourself, we know you will like it. Oh, and don’t worry, it won’t multiply after midnight if there is oil residue left on the coverstock… Or will it?
