We’ve taken the benchmark concept and created the next best innovation. The success and longevity of balls like the !Q Tour and Phaze II is no secret, but bowlers are craving more!

Enter, the Ion Pro. This is the first asymmetric benchmark ball ever designed by Storm Bowling and will be the new standard of reliability. A benchmark ball is designed to provide a balanced performance across different lane conditions. This ball is designed to allow bowlers to adjust their game without switching to a different ball. Quite simply, it’s made for players of every style from any angle. Every bowler should have this in their bag.
