Sanded Solid Reactive Bowling Ball

They tried to stop me. But my obsession cannot be contained.

Some say “winning isn’t everything.” Some say I need to relax. Relax, huh? Well, I’ve got news for them…once I’ve been unleashed, there is no way to circumvent my destructive powers and my yearning to incite violence among the pins. I crave victory. And I’m ALWAYS hungry for more. Go ahead, watch me come unhinged. But I warn you, this won’t be pretty.

My madness runs deep.

If the definition of crazy is doing the same thing over and over and expecting different results, then I’m definitely not mad. My all-new Middle Roll 70™ core gives me the almost methodical predictability of a symmetrical ball and fanatical midlane and backend motion that hits the pocket over…and over…and over…and over…

Obsession ≠ Overkill

I have an undying thirst to break out and liberate the pins from their vertical positions, but don’t get me wrong, there is a science to my destruction. My 66MH™ Solid Reactive Coverstock gives me good traction on medium/heavy oil conditions. I’m perfect for times when the MicroBite™ cover is simply too much.

It’s been awhile.

Do you remember the last time Roto Grip offered an early-rolling symmetrical ball, like me? No? Neither do they. It’s been eons. My 2000 Abralon® finish gives me more traction in oil than my late-rolling cellmate, Berserk™. Can you hear the pins quivering, yet? Don’t worry. You will.
