Roll over to Zoom

They say uncontrollable fury is a problem. I say, only if you’re in my way.

I won’t mince words. I. WANT. THE. TOP. SPOT. And when I want something, I take it. I WILL be the best this game has ever seen, regardless of what stands in my way. You have the choice to either be with me or against me. But be forewarned, if you choose to oppose my efforts, there will be no mercy bestowed upon you. Everything in my path to glory will be destroyed without hesitation. I desire to dominate. And I. WILL. NOT. BE. STOPPED.

Lots of pins for lots of players.

I don’t discriminate. If you’re with me, we will forge a path of destruction together, regardless of your style. With the same consistent, smooth-rolling Caliber™ weight block as the Bandit™, I utilize increased energy transfer to create maximum pin action for both rev-dominant and speed-dominant players alike.

The best of both worlds.

My 65MH™ Hybrid Reactive Coverstock is the ideal combination of both solid and pearl reactive. This technology gives you the ease of the pearl through the front part of the lane with the smooth reaction of a solid at the breakpoint. It’s the perfect marriage of method and mayhem.

Wreaking havoc on every surface.

I have taken all of the most destructive parts of my predecessors, the Bandit and Outlaw™, and combined them into one unstoppable force. I’m best suited for medium/heavy oil conditions, but my surface can easily be adjusted to raise hell on a variety of conditions.
