I can think of a couple of poorly designed Vekoma rollercoasters. Both are at SFWoA. First, there is the X-Flight. The flying coaster idea is a good one, unless you neglect to make certain that there is enough speed to make you feel like you are flying.
The other is Mind Eraser, the boomerang. I noticed a few things about this one--mainly train design and worthless ergonomics inside the car.
So, my question is: "How long will Deja Vu last?"
Or rather, "how bad will Vekoma screw up?"
If not at all, the ride should last quite a while. But what would it take to make a relatively short ride no longer profitable?
Unlike S:UE/V2 rides, which cash in on incredible acceleration due to the LIMs, the Deja Vu has few amazing features. Sure, there's the really tall drops, the awesome half-loop/half-corkscrew/half-corkscrew/half-loop combination. Then there's the going backwards thing. But once you get past all that, is it likely that the rides will remain in the parks longer than 5 years?
In Vekoma's defense, I have this to say: Serial Thriller is awesome!
PS- nobody get mad at me.... This was meant to be controversial... I've never been on the ride, so what do I know?
