The single belt safety harness is not supposed to go around your waist. It is supposed to fit around you up under your armpits. Those aren't safe because a fall with this type of safety belt could keep you from hitting the ground but it is also likely to break your ribs. Since all the weight of your body is being held by that one strap. I read that only a twelve inch fall can create enough force to break ribs using a single strap safety harness. I also had trouble getting used to the full body harnesses. And they are a little constraining at times. However, when the moment of truth has came and I am taking a shotthey have not messed me up yet. Hopefully they won't. My advise to you is start wearing them and just get used to them. They are much safer if you were to fall.
