The other type would be quick set up, less time/ effort invested, usually for work positioning, ie limb walking. My personal favorite is the remotely settable, remotely retrievable, transferlizer? by Lawrence Schultz, which can be used in multiple ways but this is what i usually do. Since i use a really long double lanyard, here's the thought process: doing limb walk, getting leggy, so i look up and ahead. If I have a limb up and ahead that can hold my body weight, i double crotch, either normally or with a hook.
But what if it can't hold my weight? Time for a redirect then. Throw the line over and back to you like you are about to double crotch, but clip the end on the srt line (leave the throw weight on for easy retrieval). You can clip the hitch part to your bridge, or you can clip it to a choker around the limb you are standing on. Then, possibly with no lanyard and with weight on your climb line, haul the tie in closer to the redirect while letting line out on your main system, and when it's where you want tada now you have a tip all the way out there for you that possibly could never hold your weight, and you didn't have to climb there to set it or get it. If it's tied off to the tree you can just go about everything normally, if it's tied to you then you have to maintain two systems, but can adjust your tip to any point between the redirect or the tip.
