The Track Stealth Pearl has been identified as a bowler's favorite! The Stealth core is wrapped with the QR-9 Pearl coverstock and the HK22 base to create a strong pearl reaction. This upper-mid performance ball has a clean reaction through the front of the lane, starts up in the mid-lane, and offers a fast and powerful reaction on the backend with continuation making it a desired ball when stronger balls start to react early. This skid/flip reaction is ideal on medium to heavy oil conditions.
