and yes, I'd feel VERRRYYY sorry for the guy that's done the fantastic No Limits recreation of "SW7"
Whoa whoa whao! You don't need to feel sorry for me, I enjoy doing the No Limits modelling stuff even if it doesn't turn out to be 100% accurate. I think people may be exaggerating how different the ride may actually be though. There will be differences, but I believe the ride shown on the plans is pretty much the ride we will get. One section of track in particular looks certain for a re-design, the one that connects the first batwing/cobra element to the mid-course brakes. Most people have noticed how fierce this is on the videos and I wouldn't be suprised if this was replaced with a corkscrew-like element. I also guess most of the supports will be different too.
I know the original drawings only had a NO Limits mock-up on them (rather than the official drawings for Gertslauer as per Saw) but it is most likely the case that these drawings weren't ready yet. I'm not sure where Alton Towers would stand planning wise if the ride was completely different, I know technically it doesn't need planning permission, but the building did and that was taken in context with that ride shown.
