I will agree with Soggy completely. Took the words right out of my mouth. As for giga, it too, like hyper, are just industry produced terms to classify rollercoasters at every 100ft that they top. They are rediculous, and do not accually mean 200ft or 300ft, but they are accepted, because that's what they started out being called, and that's how they remained.
P.S. When did it matter about loops? I never knew that?!?

Rollercoasters: They're not a hobby, they're not an interest, they're an ADDICTION!
