I rode WR at the end of June and WOW that coaster is awesome! But it is quite intense and it made me question myself; when will they reach the limits? I mean as intense as it is and with the structure swaying like crazy, some parts must be getting loose after a short while. I know it has to sway but maybe not so much. It must be a maintenance nightmare, and the ride is new. The elements, the pacing, etc, is perfect on that ride but I just can't see some RMCs standing very long (20 plus years) because they might become too problematic. I hope I am wrong because I think it is right now one of the best if not the best coaster manufacturer-designer on the market. I wouldn't be surprised if we start seeing more and more RMCs with a steel frame like Arie Force One.
