Ebonite Game Breaker Asym Bowling Ball Features:

The Game Breaker continues to be one of the most trusted and popular lines in all of bowling. Over the years, the core hasn’t changed much, and the cover has been updated with new technology. Ebonite is taking the Game Breaker line to the next level by shaving the sides off the core, creating the new Game Breaker Asym, a significant evolution in this historic line. The core modification increases the intermediate differential to a medium .008, just enough to see a defined difference when the shiny pearl GB 12.0 Pearl cover encounters the end of the pattern. Game Breaker fans will love this addition to their arsenal.

    Wow this ball is crazy good.

    I drilled mine 55×4.5×25. With that layout I saw one of the best skid/snap ball ever made my Ebonite.

    It’s super clean though the front of the lane and snaps back of the dry and go’s threw the pins sending them flying. This was a great idea to modify the V2 core to make it asymmetrical. I’m very excited for this.

    The Game Breaker Asym is now out and looks real good, going down the lane and with it’s shelf appeal.

    I recently took one from the drill press straight to league action. In warm ups, thought the ball was a little to clean down lane. Decided to hit the cover with 2000 siaair pad. Still not satisfied, hit it with 1500 and BAM! It gave this silver and blue asym new life. Popped off a nice 760 set on your typical house pattern.

    With a little surface adjustment, the ball gave me a nice, angular motion off the pattern while keeping that continuous motion through the deck.

    With winter leagues starting up, the Game Beaker Asym may be the ball to have!

    Ebonite has just released the newest addition to the GB line with the Game Breaker Asym. It has many of of the characteristics to the GB Pearl but they did a little modification to the core giving it a little asymmetry. I happen to have a lot of Asymmetric Pearls right now, so I drilled this a little different with a 4-1/2″ pin under the ring finger. It is extremely clean and smooth. I do like the shape and and the way it pushes through the pins. Very nice add especially for league.

    Game Breaker Asym is a polished pearl reactive with a small int. differential which gives it a little stronger move at the break. The surface gives it great length as expected, but the back end reaction with the stored energy causes the ball to go through the pins very well.

  5. TheHopeDiamond22

    The Game Breaker series continues to live up to the name and standards. Tested on the house and chromium. This one is like a boomerang with the reaction. Clean but gets started early and unleashes off the friction. Doesn’t lose energy going through the pins. Cover is very versatile if needing to slow the ball down. Able to play multiple angles. Has great shelf appeal. But the color mix looks way better down lane ripping racks. Don’t wait on this one

    The GB Asym is the evolution in the faithful Game Breaker line. If you have ever wanted that GB4 to get there a little cleaner and not miss the mid lane because you had to pick up the speed too much, TADA! Here’s the fix. The clean Cover matched up with the  V2 asymmetrical core accomplishes that perfectly.  The trusted Game Breaker line just got better.
