That plush is pretty awesome, haha
But another coaster forum I visit raised a good point: nearly every ride of a similar magnitude has had issues. Kindga Ka, Do-Dodonpa, Ring Racer, Formula Rossa, and heck the original TD had lots of downtime and troubles. Even the meager-by-comparison Xcelerator and Superman: Escape from Krypton have had their share of extended downtime issues. There just may be something inherently complicated about such massive rides.
So I don't think the blame can be placed entirely on Zamplerla, when just as many other companies have tried and also failed/experienced major setbacks. Maybe there's just a bigger lesson be learned here--a reliable technology for rides at this scale just isn't available yet.
