1. Blue Fire
2. Flight of Fear
The rest were complete garbage, but for completeness
3. Stealth
4. Speed Monster
No, really, we're into utterly and completely and moronically dreadful tosh here
5. I really can't say, they're just so pants. Maybe Thunderlooper.
Worth noting Blue Fire probably comes closest to top 10 material. Flight of fear may make top 20, but definitely top 30. Stealth and Speed Monster might drop into the top 50 somewhere (maybe Thunderlooper just getting in there) and the rest I doubt make top 100. Rita, Baco, Kanonen, RnRCoaster (yawnfest) and Velocity. Hmmmmm, Volcano actually is an odd one. I have no idea where that sits - that may be one, it's such a wierd coaster though. The launch was alright, the vertical one "curious" and the rest of the ride bland.
I don't count Space Mountain, Revolution or Back Lot Stunt Coaster because they're not really doing a launch "for the thrill", it's part of the system rather than a focal/major point of the ride.
