Who It Is Built For
Match It To Your Game
Spare Shooting
Polyester does not react to oil, so the Stained Glass holds a dead-straight line across any pattern, the tool for flushing corner pins like the 10-pin with confidence.
Beginners & Youth
A durable, forgiving first ball for learning a straight, repeatable shot, tough enough to take the abuse of the learning curve.
A Statement Piece
The clear stained glass design makes it the best-looking ball on the rack, a dedicated spare ball you will actually want to show off.
The 3 Piece Core is a symmetric pancake core, the simplest and most predictable shape in bowling. At 15 lb it measures 2.69 RG and a .006 differential, numbers built for a straight, true roll instead of hook.
That very low differential means almost no track flare, so the ball goes where you aim it, exactly what a spare ball should be: repeatable and honest, shot after shot.
The cover is durable clear polyester, the classic non-reactive spare-ball shell. It does not respond to oil, so it holds a straight line across any pattern for flush, repeatable spare shots.
The Stained Glass finish turns that spare ball into a showpiece: an eye-catching clear design that turns heads on the rack while it helps you nail your spares. USBC approved.
