These restraints almost always dig painfully into my hips. On rare occasions I'll get a good lap where they don't, though. I haven't figured out how to avoid it. I think if my legs weren't as skinny, the restraint might sit on my lap instead of stabbing into my hip joint.
I keep the vest pulled to the sides away from my collarbones, especially on Wild Eagle, just so I can take full breaths when I'm sitting on the brake run. Whatever Intamin did to make their vests comfortable, that's what B&M needs to do. Maverick is actually rideable hands up now, with no soreness or bruising afterward. Big kudos to Intamin for pulling that off.
