Define "MUCH earlier"??? Then watch the video and see if that matches your definition. That is the similar reaction I've seen from balls drilled on the rico pattern. They don't hook out of your hand and the pin from your PAP is still on average over 4.5" for most bowlers or more.
With a pearl urethane ball you can drill it to roll early but that will still be relative to the balls capability. Pearl reactive or pearl urethane isn't going to start hooking out of you hand because the ball is drill pin down. It will start to hook sooner but early still not likely.
