The oil didn’t get lighter. Your ball choice just got smarter. The Vengeance was built for medium–heavy to heavy oil conditions, delivering strength without overreaction. This all-new core and cover combination produces one of the most dynamic symmetrical balls in 900 Global history, creating a readable, confident shape that holds up from the first frame to the last. It picks up in the mid-lane, stays smooth as the lanes transition, and still finishes with purpose downlane. Strong enough to start league. Stable and predictable enough to last. Engineered for medium/heavy–heavy oil. Surprisingly good at everything else. Cover: RB 91 Solid ReactiveCover Type: Solid ReactiveSurface: 2000 Grit Core: Blast A.I.
