The selected drilling service will be added to the cart with this ball.

The Storm Purple Concept redefines how core and cover work together, delivering a level of control and consistency that reactive balls alone often cannot achieve. Part of the SPI Lab Series, it flips the usual design logic: the ARC + Pearl coverstock acts as both the engine and the tires, gripping the lane for continuous motion, while the Radius Core keeps the ball on line without locking up.

Designed for situations where bowlers traditionally reach for urethane, the Concept shines on short patterns and flat, demanding conditions, anywhere you need a smooth, controlled reaction rather than a sharp backend hook. As a two-piece ball with a thick resin shell, it combines the smooth, predictable qualities of urethane with the versatility and driving power of a modern reactive ball.
