This may have already been adressed but has anyone else noticed the part where (riders POV) you twist clockwise 180* and then a 270* ish counter clockwise into a bank? I think I saw that earlier...
I don't think anyone used those terms, but yes, we noticed. The "twists" part you mention, are coming out of a right turn, then go into a left turn, at least as far as we can tell from the available photos.
I commented earlier on how very quickly the inversion reverses direction. The g-forces will depend on speed at that point, but if there's any significant forward speed at all, the quick reversal will create a brief but serious -G.
Over-shoulder restraints will definitely be required for strong -G features.
I'm just speculating like everyone else, with the limited information we have.
