This exciting ball provides the hitting power and flare the core offers and takes the Widow polyester line to the next level with full Black Widow images. Spare balls with a performance core have been popular for bowlers who want a harder-hitting spare ball or a ball for extremely dry lanes. Never before has a Viz-A-Ball featured a high- performance core, and there's no better core or line to launch such a fantastic product.
