COVER: QR-9 Pearl (HK22) 
CORE: Stealth

Stealth Pearl features the innovative new base coverstock that has become the standard in backend reaction, HK22, and has the QR-9 additives. This ball is what you want out of a strong pearl reactive; it’s clean enough through the front of the lane to go to when the Stealth and stronger cover balls are reacting too early; it starts up in the mid-lane and has a quick and strong motion that does not stop.
