While both belong to the Ion series, the Ion Max is a step up in power and aggressiveness, specifically designed for heavier oil volumes. The Ion Pro, with its moderate hook potential, is ideal for lighter oil patterns or transitioning lane conditions. Together, they make a formidable combination, covering a wide range of lane conditions.

The Ion Max provides a strong and consistent reaction on heavy oil, characterized by a smooth arcing motion with a powerful backend hook. Its high flare potential helps it to read the lane early and maintain energy for a strong finish.

Its key differentiator is the unparalleled flare potential derived from the unique Element Max A.I. Core. This core design allows the ball to grip heavily oiled lanes effectively and deliver a powerful hook, making it ideal for tackling challenging lane conditions. The NRG™ Solid coverstock further contributes to its versatility and ability to maintain consistent performance on both polished and rough lane surfaces.

The Storm Ion Max is a high-performance bowling ball designed for heavy oil conditions. It features the innovative Element Max A.I. Core with an added weighted disk for increased flare potential (over 50% more than the Ion Pro), providing exceptional hook and pin action on slick lanes. It also has the reliable NRG™ Solid reactive coverstock, known for its superior oil absorption and consistent reaction across various lane conditions.

The Ion Max features an asymmetrical core with a low RG and high differential. This combination contributes to its high flare potential and strong hooking motion. The specific RG, differential, and mass bias values vary depending on the weight of the ball.
