For me, the discomfort is not really in the head-banging, but the loss of freedom that comes with horsecollars. I can't move my arms, I can't turn my head, I can't see around them, etc etc. The ride experience is absolutely killed when a ride has OTSR's. They may as well box me up and leave a slot for my eyes. When you think about it, all these designers can use the latest technology to get us over 300 feet and over 100 mph, yet were still using a restraint system that is essentially the same thing that was first developed in the 70's.
