I'm gonna update this list.
5. Thunderhawk, MI Adventure: I didn't like this. Ya it's a Vekoma SLC, but it wasn't so bad I wanted to never ride it again. In fact, I'd gladly ride it again. It was just really bad compared to the rest of the roller coasters I've ridden, and really good to the other bad ones.
4. Magnum: Ya, it has amazing airtime, and ya it's a classic, I just hate it for some reason. Don't question it.
3. Woodstock Express, CP: Another Vekoma, but a family credit. Just rode it recently (Friend doesn't like coasters very much), and it was so rattly, and so uninteresting, that it wasn't enjoyable. At least Thunderhawk had something interesting about it!
2. Great Pumpkin Coaster: +1. Bad.
1. Corkscrew, CP: Terrible. Needs to die soon. Get vekoma to retrack if you want to keep it, just do something with it!
