A Sleek, Dependable Spare Ball
About the Dragon Midnight Poly
The SWAG Dragon Midnight Poly is built to do one job and do it perfectly: convert spares. Its sleek all-black midnight finish keeps it simple, but its real value is precision. This is a polyester ball engineered to go straight, so you can pick up single pins and corner pins with a repeatable shot.
The Dragon Midnight Poly pairs a simple, low-flare 3 Piece Core with a durable polyester coverstock. Plastic is the least aggressive coverstock material, so the ball ignores the oil pattern and travels in a straight, predictable line. It is the dedicated spare tool every complete arsenal needs, in a clean, classic black.
Understanding the SWAG 3 Piece Core and Polyester (Plastic)
SWAG built the Dragon Midnight Poly to go straight. Specifically, the simple 3 Piece Core has a high 2.69 RG and almost no differential at .006, 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. The full specifications are listed below.
A Simple, Low-Flare Core Built to Go Straight
The Dragon Midnight Poly uses a simple 3 Piece Core with a high RG (2.69 at 15 lb) and almost no differential (.006), 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 ball rolls on a straight path regardless of the oil pattern. That predictability is the whole point of a dedicated spare ball: you can throw the same straight shot at every single-pin and corner-pin spare and trust it to get there.
A Durable Polyester Cover With Minimal Friction
The Dragon Midnight Poly is finished with a polished polyester coverstock in a sleek all-black midnight design. 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 ball pushes straight through the fronts and resists the hook of a reactive ball, so you can line up your spares with confidence. Polyester is also extremely durable, making this a long-lasting, dependable tool in any bag.

BowlersMart Tips: Where the Dragon Midnight Poly Fits in Your Arsenal
Where It Fits in Your Arsenal
Every complete arsenal needs a dedicated spare ball, and the Dragon Midnight Poly fills that role. Where your reactive balls hook to the pocket, this plastic ball goes straight, so you use it for corner pins and single-pin spares where hook only adds risk. It is the simplest, most predictable ball in the bag, and one of the most important for protecting your score.
Surface Adjustments
The polished polyester surface keeps the Dragon Midnight Poly clean and skidding straight. There is rarely a reason to change a spare ball’s surface, but your pro shop can re-polish it if it ever loses its shine. Keep it 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 ball shooting straight and looking sharp for years.
