The list isn't actually classic coasters, it's just coasters that meet a stupid criteria they have. Triple Hurricane was on it lol.
* The coaster must use traditional lap bars that allow riders to experience so-called airtime, or negative G's (that sensation of floating above the seat!!). Individual, ratcheting lap bars do not meet this requirement.
* ACE Coaster Classics allow riders to slide from side-to-side. A coaster with any restraint or device that restricts this freedom is not eligible for ACE Coaster Classic status.
* ACE Coaster Classics allow riders to view the upcoming drops and thrills. Coasters with headrests on every seat, or the majority of seats, restrict this view and are not eligible for ACE Coaster Classic status.
* On ACE Coaster Classics, riders are free to choose where they sit. Some parks' operating procedures assign seating; these coasters are not eligible for ACE Coaster Classic status.
That's what it has to have to be on their list. It's mostly kiddie coasters and scenic railways that actually meet the requirements.
