In general, I've found Brunswick equipment to roll earlier and be more smooth/even than Storm equipment. So my advice would be to find the most even pieces in Storm's line and get that rather than trying to out-and-out copy a Brunswick ball. As has been suggested, the Dimension is going to be a good match because of its evenness. If you can find either of the Thunderstruck balls, those would probably work, too.
