RE: 4 Point harness necessary?
If you are looking for someone to say that a single strap is the way to go, you probably aren't going to get it. If you are just suspended by the chest, that is a major jolt to your spine because all of your weight going down (legs, abdomen) is going to have to support that entire weight with just your spine. Also, a belt around the chest is not very comfortable, so the tendency is to push it down more closer to your waist, which poses a second problem, and that is that your weight is going tobe top heavy, causing you to flip over, and that is about as bad a position as your can be in, especially unconcious. The four-point may be a bit of a pain to put on, but that little extra effort is all worth it when you aren't going on disabled hunts because you fell and broke your back.
