Track Stealth
PBA Approval Date
Release Date
Discontinued

In recent years, symmetric Track balls have offered a medium to low flare potential, creating a more controllable reaction. The Stealth breaks out of that mold with more flare and more technology. 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 its low RG and high differential combination.  

We wrapped the new Stealth core with the QR-9 (Quick Response) cover. The QR-9 cover is known for its strength in oil and maintains a strong reaction at the breakpoint.

QR-9 Solid Coverstock
Type
Solid Reactive

The QR-9 cover was first featured on the original Paradox in a Hybrid version. Now for the first time, we bring you a solid version of the QR-9 series. The QR-9 Solid coverstock is designed to work best on medium to heavy oil. It will give good traction in the midlane with plenty of continuation on the back end and through the pin deck.
