La Ronde always use french name for their ride, except for proper noun like "Goliath" or words that doesn't really exist like "Gravitor". Vampire is a french word, Demon is also a french word, Boomerang is also accepted as a french word. They already made announcement for Gravitor, so that's why they just kept the same name. The won't use "mass transit with a twist" anywhere, it's juste the way six flags describe the ride on the video.
Gravitor was originally supposed to be a Gosetto "Party Dance" ride. Very small ride that looks like a shopping mall ride, not a Six Flags amusement park type of ride ! I'm glad they went with the rush street flyer instead.
I looked at a lot of videos of the Rush Street Flyer and it looks very slow to me. We used to have a Zierer Flying Carpet 10-15 years ago that was CRAZY FAST. Is the Rush Street Flyer a good ride ? Any airtime at all ? Any good sensation? In every comments I read about Rush Street Flyer, people seamed to love this ride, so I guess it isn't that boring at all.
As for the location in the park, I was told that the "Avenue Adventure" with the Gravitor and the new Flying Scooter ride called "Phoenix" will be behing the Demon ride (Mondial Roll Over), next to the Huss Pirate. That's funny because the Huss Rainbow that La Ronde used to have in the 80's was where the Huss Pirate is sitting today, and later, in the 90's, the Zierer Flying Carpet was almost right next to the Pirate, where the new bumper cars are.
Huss rainbow in 1985 (with Le Monstre wooden coaster in construction at the background and the first pirate ship that was later replaced by the flying carpet). The rainbow used the french name "Arc-en-ciel"
And Zierer Flying Carpet. La Ronde used the french name : Tapis Volant. Still the name was written in German on the ride itself, the ride came from germany. At the back we can see the new Huss Pirate sitting were it still sits today, were the rainbow used to be.
