My money's with mini.
I do the civil helicopter thing as winch operator/cargo sling crew and once or twice as the dope on the rope
. Getting me out the door on that suddenly
very thin cable was in hindsight quite funny but at the time anything but. 
I can sit with my feet out the door with no problems as I am tied to the aircraft, but a 4 step ladder is eneough to give me a cold sweat. As for skyscrapers etc......forget it!
