The oil didn’t get lighter — your ball choice just got smarter. The 900 Global Vengeance is built to take on medium–heavy to heavy oil with confidence, delivering power without the violent overreaction that can make tougher conditions unpredictable. Designed with an all-new core and cover combination, the Vengeance stands out as one of the most dynamic symmetrical bowling balls ever released in the 900 Global lineup. At the heart of the Vengeance is the Blast AI core, featuring the highest differential in the Global line. Its single-density design promotes a strong, readable mid-lane motion while retaining plenty of energy to finish with authority downlane. Wrapped in the RB91 coverstock—one of the strongest covers ever used on an 800 Series ball—the Vengeance quickly absorbs oil to handle today’s heavier volumes with ease. The result is a smooth, stable reaction that starts strong, adapts as the lanes transition, and stays reliable from the first frame to the last. Strong enough to open league play, predictable enough to stay in your hand all night, and surprisingly versatile beyond its intended conditions, the Vengeance is a smart, dependable choice when oil is not your friend.
