Yes, Mr. Hyde was a re-located freefall, which began life at Six Flags Great America as The Edge. There was an accident (non fatal) on this ride which caused SFGAm to sell the ride in which Rocky Point Park (now defunct) in Rhode Island, bought it. When the park was auctioned off, Premier Parks purchased the ride and moved it to then Geauga Lake for 1997. It has a new (ugly) paint job for 2000 - purple and lime green.
Yes, Double Loop finally received a great paint job for 2000. It has yellow track and purple structure. The coaster used to be all black for years and the paint was starting to come off in places, exposing the original white track (anyone else notice this?). Rumor had it the ride was doomed with the Six Flags makeover but the paint job dispelled those rumors. Double Loop may not be the biggest or loopiest(?) out there, but she has been known to be the smoothest Arrow coaster in existence.
