To the average guest though, Swarm and Inferno's seating arrangement are different enough to have 'a place' in the line-up as it were... At SFMM there's 3 coasters that focus on multiple inversions (Viper, Riddler's and Scream), but the park is big enough really to get away with that (plus Viper has a lower height limit, whilst Riddler's has the stand-up feature/burden)...
Problem is at Thorpe, Colossus is the world record breaker, and I don't feel that the Floorless idea is enough of a differentiate for guests (aside from the fact it won't attempt to break your neck) to give much of a damn towards a ride that lacks much in the way of a gimmick in comparison...
