Gazprom the ride was all right
(I found it very funny that Blue Fire was sponsored by such a controvesial company!) The main good thing about the coaster is the restraints. It's very nice to go through loops etc and still have the freedom of only a lapbar.
The coaster itself is a little bit too forceless for my taste. But I guess that's why it is such a big hit at Europa Park. Everybody can ride it, even fairly young children (height restrictions are only 130 cm).
The launch is weak and the following top hat is taken too slowly, you almost feel like you're gonna fall down sideways while you're at the top.. The following loop provides some nice hang time wich is a lot more thrilling with these kind of restraints than OTSR.
Then we have the crazy right turn which is one of the few intense bits of the coaster. The turn is banked 90 degrees but barely turns at all so you get thrown up in a strange way, awesome! After that it's the mid course brakes where you get some nice air time in the front (only the 2-3 first seats).
Next up is the horse shoe element with a couple of forceless corkscrews but yet thrilling because of the restraints who allows your body to fly around. The turn in the horse shoe on the other side has som great g-forces!
The "air time hill" through the loop is slow and do not provide any air time that I could feel. The following helix is sadly really weak as well. Then follows the best element of the coaster :--D the amazing heartline/inline roll! It looks like a heart line roll but feels more like an inline hence you get thrown out of your seat and are only hold by the lapbar. You feel a combination of "oh my god I'm gonna fall out and die" and "damn this is so awesome"!
In total the coaster is nice because of the restraints, the headchopper effects from the rocks, the otherwise great theming including the preshow, cuz it's smooth and in that it feels "different" (not the same old B&M/Intamin recreations that has been done to death). The bad things are that it is a bit slow and forceless, and that it is too short and low compared to the really big mega loopers like Dragon Khan.
Anyway I still enjoyed the coaster a lot!! And belive it will become a big hit for Mack since it appeals to such a wide audience. But I do still rank Dragon Khan as my favourite mega looper!
Edit
