Whats up with Shockwave at Kings Dominion?

I'm a coaster junkie and Cedar Point is my favorite place on Earth, but to this day I have NEVER been on a stand-up coaster that was remotely comfortable. I personally hate them and yes, the restraints are a bear and the shorter you are the more they hurt. My girlfriend is your height and at 5'1, your head lies right between the shoulder restraints, which means every twist and turn bangs your head from side-to-side off the pads. Not comfortable. The restraints don't cover your legs at all, you just stand up and the seat under you adjusts to your height. Then you pull down the shoulder restraints which are just like the ones on many other sit-down coasters and you're set to go. Mantis at Cedar Point is probably the least painful one I've been on but I still don't really like it and I've been on many of these rides.
