Storm Ion Pro Bowling Ball ? The New Gold Standard in Benchmark Performance Storm introduces its first-ever asymmetrical benchmark ball?the Ion Pro, designed to be your go-to option for reading the lanes with precision and confidence. Building on the legacy of fan favorites like the !Q Tour and Phaze II, the Ion Pro redefines versatility, offering a smooth, readable motion that suits every bowler, from every angle. At the core of the Ion Pro is the Element Tour A.I. Core, an innovation in shape and balance. Its stacked ellipse design features a wide central mass, which lowers the RG to 2.47 and adds controllable asymmetry. The result? A strong mid-lane read and 4?5 inches of flare potential, making it adaptable to multiple layouts and playing styles. Wrapped in the time-tested TX-16 Hybrid Reactive coverstock?originally made famous by the Phaze II?the Ion Pro balances front-lane length with backend strength. Its 4000 Grit finish makes it perfect for medium oil conditions where consistency and forgiveness are essential. Whether you're a tournament bowler or league player, the Ion Pro is your new benchmark for predictable power, lane control, and style?all in one striking Blue/Grey package, finished off with a sweet Kiwi Tart scent.
