I *think* the 'true' definition of a hypercoaster is a steel coaster with a hill and/or drop +200, made in a style to mimic (older) wooden coasters. This originally had a "out&back" style connotation. Since that was the general feeling, that it had to be a steel out&back, several other related terms were spawned, such as hyperlooper (Steel Phantom), hypertwister (Raging Bull) and hyperwoodie (SOB). ME best falls into the hyperlooper catagory, because it does have a 200+ hill (though the drop is much less) and it has inversions. High Roller (AFAIK) has NO hills and NO 200+ drop and therefore is not a hyper-anything.
Is that as clear as mud to everyone? Good! =]
