Roto Grip Gremlin Bowling Ball

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.
