Solid Reactive Bowling Ball

It wasn’t even a fair fight.

When I hit the lanes, it’s a no-holds-barred fight for victory. I come in with a fierce punch and beat down my rivals with every pin I crush. I’m all about putting the big hurt on the competition. But what I won’t knock out is your bank account – that just ain’t cool. So next time some alley chumps want to battle, tell ‘em “Let’s Rumble.”

I’LL NEVER SHY AWAY FROM A FIGHT.

When it’s time to brawl, I’m in. My new Late Roll 51™ core helps me deliver devastating blows, good length and strong down-lane motion that leave my challengers crying for their mommas. Hey, if they don’t like getting smacked down, then they shouldn’t step up.

ROCK SOLID AND FULL OF POWER.

These good looks aren’t just for show. My new 55M™ solid reactive coverstock gives me the upper hand to easily clear the frontend and bring my hard-hitting punches down lane. I’ve got no problem making the pins feel my strength over and over again.

IT’S ALL ABOUT CONTROL.

In case you didn’t know it, medium-oil lanes are my territory. I don’t plan on giving up my control in these conditions to anyone. Got it? And when you get me together with my boys the Wrecker™ and Shatter™, oh man, we’re ruthless. I’m glad to see you’re standing with us because if you weren’t, things could get ugly real quick.
