A Collectible Spare Ball
About the Norm Duke Limited Edition Clear
The Storm Norm Duke Limited Edition Clear celebrates one of the most accomplished players in PBA history with a clean, collectible polyester spare ball. It delivers the predictable straight-line reaction every arsenal needs, wrapped in a clear design that pays tribute to a Hall of Fame career.
As a polyester ball, the Norm Duke Clear pairs a simple, low-flare 3-piece core with a clear plastic coverstock. Plastic is the least aggressive coverstock material, so the ball ignores the oil and travels straight to your target, the dependable, no-hook tool for converting spares with confidence.
Understanding the 3 Piece Core and Polyester (Plastic)
Storm built the Norm Duke Clear to go straight. Specifically, the simple 3-piece core has a high RG and almost no differential, so the ball produces essentially zero track flare, while the polyester cover generates very little friction with the lane. As a result, it holds a true, predictable line regardless of the oil pattern, exactly what you want when shooting spares, in a limited-edition design worth keeping.
A Simple, Low-Flare Core Built to Go Straight
The Norm Duke Clear uses a simple 3-piece core with a high RG and almost no differential, numbers that produce essentially zero track flare. That is exactly what you want in a spare ball: the core resists hooking, so the ball holds a true, predictable line straight to your spare.
Because it does not flare, the Norm Duke Clear rolls on a straight path regardless of the oil pattern. You can throw the same straight shot at every single-pin and corner-pin spare and trust it to get there, the kind of dependable consistency that defined Norm Duke’s own game.
A Durable, Clear Polyester Cover With Minimal Friction
The Norm Duke Clear is finished with a clear polyester (plastic) coverstock. Polyester is the least aggressive coverstock material, so it generates very little friction with the lane. The result is a clean, straight reaction that ignores the oil and goes where you aim it.
That minimal friction is exactly why plastic is the standard for spare shooting. The Norm Duke Clear pushes straight through the fronts and resists the hook of a reactive ball, so you can line up your spares with confidence. As a clear, limited-edition piece, it is also a collectible tribute that is as nice to display as it is to throw.

Surface Adjustments
There is rarely a reason to change a spare ball’s surface, but your pro shop can re-polish the Norm Duke Clear if it ever loses its shine. Keep it clean and polished so it continues to travel straight through the oil.
Coverstock Care
Wipe the polyester cover with an approved ball cleaner after use. Plastic is durable and low-maintenance, so a quick wipe keeps the Norm Duke Clear shooting straight and looking sharp for years.
