Coaster types ALWAYS go through bandwagons though... Look at SLCs, Boomerang, Stand-ups, Inverted, Accelerators and probably many more... When these types were introduced there was a fairly high amount of boom due to various reasons due to cost, ease of construction and uniqueness (by which I mean, unique to the park/area when it opened)... Indeed, even the Flying coaster had a boom, the only one that really didn't was the Dive Machine, but that easily could have been due to the high cost of ground/tunnel work...There's absolutely nothing wrong with Wing-Riders doing the keyhole element... By that reasoning to a degree, Inverted coasters are all the same as they use leg-choppers on all of them... There are a lot more samey coasters in the world than 3 (potentially 4) Wing-Riders... The American side of the industry is so damn different due to the vast gulf in tastes... Bigger, bolder and brasher are the key things you see in every American park, even Disney do big things with everything... I like the look of the Superman ride (bar the brakes of DEATH) as it is a really unique ride... It's confirmed as a Premier since I posted that stuff yesterday...And if you're expecting Six Flags to give a well detailed story or theme PAST DC Comics? Never gonna happen...
