Of all the recent Quantum releases, the Quantum Bias has been my favorite. Needless to say, I was interested to see what the Bias Pearl was going to do. For me, the Bias is the ball that is guaranteed to go longer for me than anything else in my bag. With a 2.56 RG and a 0.052 DIF, the ball is designed to go longer. Then, you put a pearl cover on it and this ball is a perfect combination for me when I need to get the ball down the lane and recover on the backend. My ball speed tends to be more moderate than some of the modern players out there so getting this ball to pick up for me early is not going to happen. However, when the fronts are fried and I need to get the ball downlane, this ball is perfect!
