However, when we look at KD by comparison - the prototype S&S air-powered launch coaster purchased straight from the test lot with some minor modifications but not ready for prime-time in Hypersonic XLC; Volcano was the first full-circuit Intamin LIM launched inverted coaster (sounded like it was also a prototype, though not straight from a test lot). If I remember correctly, I-305 is the first major coaster from Intamin with the double spine - I would say the unique combo of elements makes it like a new ride concept, but tbh it's an Intamin that pushed some boundaries like they do, so par for the course.
