Hello all! I've never posted here before, but I figured I'd take this opportunity to join and contribute my two cents to this discussion.
Anywho, I feel that I have "cracked the code" for how to ride SkyRush without any pain from the restraints. At least, it works for me and it seems to work for everyone else I tell. The trick is to push your butt a bit forward so you're not completely against the back of the seat. When in this position, the lap bar no longer makes contact with the thighs, but hits you directly in the waist. No legcrushing, no pain. I tried to add a picture but i can't figure it out!
