We will determine the layout by consulting with a dedicated driller while you send us a measure sheet, etc., so please feel free to ask any questions you may have. This is a new Storm ION MAX ball from Hi-Sports. Please refer to the outer box in the photos for the specifications. The following is quoted from Hi-Sports: The ION, which uses Storm's asymmetric core A.I. technology, has been loved by many bowlers as a ball with an excellent balance, showing amazing run and hook despite its incredibly low inertia. This time, the ION MAX has added a flip block to the weight block of the Element Tour core and covered it with an NRG SOLID cover that is strong against oil from the front to the middle of the lane. It shows a sense of stability that you wouldn't think was solid until the middle of the lane, and the stopping feel at the breakpoint and the width of the back-end hook give the impression of throwing a hybrid cover ball rather than a solid cover ball. That's how effective the flip block is, and the hook at the pin has been improved compared to the original ION. Of course, the pin action is intense. It's a satisfying ball with pin carry that exceeds expectations. Coverstock: NRG Solid Reactive Core: Element A.I.
