Road Warrior is going to be the absolute replacement for the iconic Hy Road Pearl. With the Inverted FE2 AI core and R2S Deep Pearl cover this ball makes a similar motion as the Hy Road Pearl but maybe a couple of feet sooner. I drilled mine 4.5 x 4.5 and I absolutely love this ball when the left side gets fried. It really allows me to either stay on top of it longer or even open my angles up and watch it hook down lane. This ball will an absolute hit later in blocks when you need something to really get through the front half of the lane. If you want to replace your Hy Road Pearl or just looking for direct replacement than look no farther.
