I've done 11 and they are mostly a one and done so cannot recall much detail any more. The focus was often just making sure I was comfortable in the weird restraints.
From what I remember, these are my best to worse with the ones I don't remember in the middle as they cant have offended me too much:
1. Milky Way (Togo/Greenland) - No Inversions, duels with another ride, air time with bouncy restraints, a little but cute - a genuinely enjoyable ride and not because its obscure.
2. Shockwave (Intamin/Drayton Manor) - The first stand up I rode and very early in my coaster history. Has held up over time but (somewhat thankfully) rarely visit the park. Not a great station or queue. Always loved the zero G and find it a shame that element wasn't used on other stand ups. A bit short but longer rides leave you clenching for too long.
3. Shockwave (Togo/Kings Dominion) I was pleased with how 'ok' this was, may even have cracked a smile.
4. Georgia Scorcher (B&M/Over Georgia) Was in the way of Goliath so wasn't that interested but was fine.
4. Green Lantern (B&M/Great Adventure) Didn't ride as Chang and don't see what all the fan boy fuss was about, but was fine.
4. Standing Coaster (Togo/Rusutsu Resort) Love the lift through the loop but barley remember the ride.
4. Cobra (Intamin/La Ronde) No idea, at least I got on but was a credit heavy day in a park I wasn't entirely keen on so didn't linger in case I had to go back.
5. Riddlers Revenge (B&M/Magic Mountain) Not a fan but would ride again. A better restraint than some others is my clearest memory.
6. Skyrider (Togo/Canadas Wonderland) I have a note from a long time ago saying I wasn't into this one - don't remember why this was so interesting to see what other people thought and that I liked Kings Dominion. Maybe I was wrong, or maybe its just that Behemoth had become my favorite ride at the time and the park had nothing else that close. Better than the woodies there I guess
7. Vortex (B&M/Carowinds) No interest riding on my second visit and my friend was happy about that.
7. Iron Wolf (B&M/Great America) Very happy to ride B&Ms first work but otherwise, no.
Didn't ride Mantis before it was converted to Floorless. Very disappointed in that as it was heavily featured on the first Roller Coaster program I ever saw and binged watched. If anyone has a clip of "Extreme Machines - Roller Coaster" I would shed a tear in joy. Although Rougarau's main greatness was being in a swamp so perhaps I didn't miss out.
