^^Hmm, so maybe more like the el loco restraints from S&S? I'm not sure that's much better. If anything has to go over the shoulders, I'd prefer it be more like Intimidator 305's padded straps.
It's certainly not an issue of safety in any case. As others have mentioned, a number of coasters have operated for decades with inversions and nothing to hold riders in but simple lap bar restraints and they have been fine. Even with the hang time that this ride might provide, with a properly designed lap restraint you can still hold riders in their seats while inverted. If it does end up with OSTR's, I'm betting it's because management at some level is paranoid after the Darien Lake incident. Either that, or something to do with trying to accommodate larger guests at the same time as smaller ones.
