Word of Warning: When entering the ejector seat, lock the bar down as far as it goes on your legs. If you think it is tight, try like hell to lock it down one more notch. This will prevent it to beat and bruise the hell out of your legs.
I had one very painful experince when I was in 1-3 once. I didn't lock it down all of the way, and I paid for it. On EVERY bunny hill it DIDN'T hit my legs, it hit another region down there. Can you guess where?
