One thought I had when I saw this was that this could actually be B&M getting closer to what the TOGO stand ups were like -- and I sincerely welcome that. I honestly really enjoy stand up coasters and I loved all 3 of the Paramount TOGOs a lot but the B&Ms just have a headbanging issue that makes them hard for me to ride. These restraints could very well be a revival of the stand up -- as long as people look at them with an open mind. Too often preconceived notions ruin something in this industry.I started saying the B&M standups should be converted to vest restraint standups after riding Firebird. (though a conversion would need to be 3 wide).
Standing can increase intensity and vulnerability -- make you feel like it could fling you off. Unfortunately I don't know of any B&Ms that feel like that, but Shockwave did. Shockwave was also an appropriate size (and simplicity) to need the intensity.
Headbanging is a definite negative on all B&M standups, which should be eliminated by vest restraints. Neck/jaw banging should be eliminated by non-Togo restraints. Hopefully B&M will finally see fit to include movements suited to standing, such as airtime. Launching should be good.
