A serious spare weapon for serious bowlers. This Viz-A-Ball provides real hitting power and flare thanks to a performance core, taking the Widow polyester line to the next level with full Black Widow images.

Performance-core spare balls have been popular for bowlers who want a harder-hitting spare or a ball for extremely dry lanes. Never before has a Viz-A-Ball featured a high-performance core — and there's no better line to launch it than the Black Widow.

Who It's For

• Spare shooters — harder-hitting spare motion with real core flare.
• Dry-lane players — polyester control when the lanes are burnt.
