Roto Grip and 900 Global, sister brands under Storm Products, released four new performance bowling balls for June 2026: the Roto Grip Hustle VP (value pearl with length), Roto Grip Hustle SOS (versatile all-around hybrid), 900 Global Vengeance Returns (early-reading medium-oil benchmark), and 900 Global Viking Conquest (strong asymmetric heavy-oil weapon). They span $114.95 to $199.95 and cover everything from light to heavy oil. All four are available at BowlersMart with always-free shipping and 60-day returns.

The 900 Global Viking Conquest is the strongest. It uses the asymmetric Strobe A.I. Core and the RB 94 Solid cover, the strongest coverstock 900 Global has used under its current rating system, at an aggressive 2000-grit finish, making it the heavy-oil piece of the drop. The 900 Global Vengeance Returns is next, with the highest differential of the four (.055 at 15 lb) for a hard-driving medium-oil benchmark. The two Roto Grip Hustles are the most controllable, built for light to medium oil.

Both use the same proven symmetric Hustle Core, so they share a smooth, repeatable personality. The difference is the cover. The Hustle VP uses a VTC Pearl cover at a Power Edge polish, which clears the fronts cleaner and creates a sharper, more angular backend, so it is the length-and-angle option. The Hustle SOS uses a VTC Hybrid cover at a 4000-grit finish, which reads the midlane earlier and smoother for a versatile, all-around reaction. Many bowlers carry both: the SOS for the fresh and the VP as the lanes dry out.

They target different conditions. The Vengeance Returns uses the symmetric Blast A.I. Core and the RB 91 Hybrid cover at a Power Edge finish, making it an early-reading, controllable benchmark for medium oil. The Viking Conquest uses the asymmetric Strobe A.I. Core and the stronger RB 94 Solid cover at a 2000-grit finish, making it a more aggressive piece built for heavy oil. Pair them together: the Viking Conquest for the fresh and heavy volume, the Vengeance Returns as the lanes transition to medium.

They are sister brands. Both Roto Grip and 900 Global are performance bowling brands manufactured by Storm Products, which is why they share reactive coverstock technology and finishes like Power Edge. Roto Grip is known for value-driven, versatile equipment like the Hustle line, while 900 Global builds higher-performance pieces like the Vengeance Returns and Viking Conquest. Together this drop spans the full range from entry-level value to top-shelf heavy-oil performance.

The Roto Grip Hustle SOS at $114.95 is one of the best values in bowling, delivering proven, elite-level performance at an entry-level price. Its VTC Hybrid cover and smooth Hustle Core give a forgiving, all-around reaction that handles most house shots. If you want length and a sharper backend as the lanes dry out, add the Hustle VP at the same price. If you face heavier oil, step up to the 900 Global Vengeance Returns as your benchmark.
