does anyone think with the dramatic twist heading downward from 400+ at 100+ mph will require otsr's? would seem scary without. I cant image taking the back spiral on WT without otsr's. This would be similar.
I doubt that it'll need them. Xcelerator got by without them.
If the lapbars weren't perfectly safe, they wouldn't be used. Batman and Robin at 6 flags great adventure have lapbars, and they even have inversions.
