I am really having trouble understanding the purpose of all these suspension setups. What advantage is there with all the rings, prussics, etc? I use webbing on either side. One side I tie a fixed knot and on the other side I tie an adjustable knot (trucker hitch, i think). My tarp has two guy lines that I attach to the same trees and stakes down to the ground at another 6 points. This setup has work flawlessly so far.
What am I missing here?
