Read the instructions on how to install a Friction Saver (False Crotch) in the Tree Climbers Companion book. It is not that difficult and it would make your climbing easier if you like to go into the effort to use one.
I do not use them that much because I do not like the tie radius that the rope makes while entering and exiting the rings in the saver. Also i notice that sometimes the pulley jams into the ring at one weir angle that creates more friction than I like to deal with. Arborists use something similar a (Rope Guide) that appears to do a better job.
