Super Trooper saves the day! Its controlled performance inspires even the casual bowler. With the extremely popular Rock On core body, no flip blocks and a lower Rg to create less flare. Count on an earlier roll with a smooth backend reaction. Its Super-Flex coverstock is impressively sharp in polished black/violet with silver sparkle logo. And a great value to boot. Territorial on medium to dry lanes, this Super Trooper plays for keeps.
