After riding Firechaser Express recently, I'm more eager than ever to see a version of it at SDC soon. It's really the perfect family coaster. The show building was awesome and really turned it from just a little coaster into a complete experience that was fun for everyone. I don't care that we already have PK, Firechaser is a definite step under PK's intensity and the show/backwards element adds some uniqueness anyway.
As for the wing-coaster rumors/wishes, Wild Eagle didn't impress me at all for some reason Wild Eagle felt... off. Like it was originally designed as a sit-down coaster and the radius of the loops are slightly wrong. I actually greyed out in the vertical loop a couple of times even though it didn't feel that intense. It just felt slightly uncomfortable, and the meandering figure-8 at the end didn't add much to the ride either. It should have just been a floorless coaster, IMO.
Thunderbird at Holiday World, on the other hand, was a blast. The launch is great and it's very re-rideable. If we get our own Wing-rider, it better be something like that.
