15 lb. 2 oz weight. 2.9 top weight pin 3-4" Excellent heavy oil ball or for those slightly slicker lane conditions that require ball strength and a little earlier roll. Wrapped in the QR-9 (Quick Response) Solid reactive coverstock, finished at 500/1000/1500 Siaair, Stealth will power through heavier oil while retaining energy for a strong backend finish. Paired with the Stealth symmetric core, you can anticipate a strong and reliable overall hook. Here's what Track has to say about Stealth: It's been a while since Track offered a ball like the Stealth. The Stealth core is a new design and features a dense flip block on the bottom of the core mass, helping the Stealth maintain differential numbers after drilling. Bowlers wanting more performance from a symmetrical ball will love the Stealth because of it's low RG and high differential combination. FREE SHIPPING - Cont. United States only Must pay by Paypal
