The Ion Pro Pearl is Storm’s latest ball to use the Element Tour AI asymmetrical core.

Instead of being shined with Power Edge, the cover is finished this time with 4000-grit Abralon. Despite being a pearl, we saw slightly less length from the Ion Pro Pearl than the Ion Pro Solid.

This ball was a more angular option than the Ion Max and the Bionic, but it didn’t have
