Yeah, Supes The Ride does look a lot like Jinx. It starts with a sidewinder (instead of cobra roll) and goes into a mass of twists and turns before a single corkscrew. A lot of people really love it at MGM, but I thought it was just okay. Without the amazing Disney themeing I think it would be a dud, honestly.
By the way, you can read all about it in First Drop Issue #50, p21.
