Slammer, Rush, Saw, Inferno are all pretty complicated rides too.. Saw and Rush being prototypes, I'm pretty sure Slammer is very different in the way it works to the one which was / is open in the states, Not sure about inferno but its Pre lift drop compecates things a fair bit and with another rumoured to open in 2012 too. As I said, not just rides too but general things, project link and Iphone apps for example, I think we will be seeing more like that in the future too. Its just allway's the impression ive got from the park.Edit: I'm in no way saying this is what makes them good rides and what not.
