Both X2 and Maverick feature unique elements that make them both amazing rides. X2, formerly X, was the first 4th dimension coaster ever. This means that the seats ride on thier own rails, and spin independant to the movement of the train, making for an incredible, out-of-control experience. Maverick also pushes the envelope of coaster design. Featuring a LSM launched lift hill, an another launch from a rolling start in a pitch black tunnel, Maverick is no slouch on the thrill either. To make a good descision, make sure you check out both ride pages.
