Now that I think about it, adding an inversion on a giga would be a bit too intense. It might cause people blackout problems or throwing up for someone even who doesn't have a weak stomach.
I think they are pointing towards the name and answers inside the posters themselves. They keep on saying look at the posters next time you go. They are trying to get you to notice something weird in the posters.
I don't know what the problem is with people saying Millennium Force isn't forceful. I think it is very forceful and intense. I think the speed kind of takes your mind off the forcefulness and focusing on the fun.
Well, if not an inversion, maybe there is something we have never seen before on a b&m hyper or giga, like that dive loop element on Hyperion at Energylandia.
Not technically an inversion, but still a cool element.
