Brunswick's successful relaunch of the Quantum product line continues with the Quantum Bias Pearl. This bowling ball features high-density Quantum Mushroom High RG Asymmetric cores along with a thicker urethane coverstocks. This thicker coverstock offers durability, longevity, and massive hitting power. This ball is unique in that each core has a unique design to compensate for the gross weight of the ball, the core's dynamics, and the balls hook potential. The Bias Pearl uses Brunswick's ECA-XR Pearl coverstock formula to glide through the front of the lane and end with a strong backend reaction and excellent pin carry on medium oil lane conditions.

I loved the 1st Bias. But I couldn't throw it pass the first game. This new Bias is the perfect compliment. Not only does it still get through the front of the lane clean, it gives much added length but still has the at original Bias Motion in the back. And nothing beats that Quantium sound when it hits the pins.
