Aion Max 15 lbs, New The ION, featuring Storm's asymmetrical core A.I. technology, was beloved by many bowlers as a ball with an excellent balance, showcasing remarkable roll and hook despite its low inertia. This ION MAX adds a flip block to the weight block of the Element Tour core and is wrapped in an NRG SOLID cover, which is strong in the mid-lane oil. It shows a stability that you wouldn't expect from a solid cover until the mid-lane, and the stopping feel at the breakpoint and the width of the backend hook give the impression of throwing a hybrid cover ball rather than a solid cover. That's how effective the flip block is, and the hook before the pins has been improved compared to the original ION. Of course, the pin action is intense. It's finished as a satisfying ball with pin carry that exceeds expectations. Coverstock: NRG Solid Reactive Core: Element A.I.
