Last couple hunts my tether friction hitch (hitch rope came with the muddy lifeline) started acting up and wanting to slip. So I got on EWO and got 6mm eye2eye 22"....main line is rescuetec....
3 wrap prusik wasn't holding, 4 wrap I couldn't break easily enough for my liking, same with asymmetrical 3/4over1....so I was playing around with all these fancy/exotic hitches.... First thing, 22" is too short for my preference....and being too short limits which fancy hitch u can use ...only a few that are mentioned on this thread....in hindsight I should have just ordered 10-20 feet of hitch cord so I could have tied and cut to the length I prefer.....anyway, ..knut hitch is what I ended up with...a little frustrating to tie with a rope that's kinda short but once dressed, weighted, and the knot tightened....wow that joker works smooth...still using a tender even thought it probably not needed, but it is almost effortless to get that hitch to grab and let go....
as far as heat goes if u rappel on just a hitch.....I'm descending on a monster munter with a prusik backup (prusik retired and knut taking it's place)....the carabineer connecting my bridge to the MM gets pretty warm especially if u rappel a long way or go down fast... The back up friction hitch above the MM generates a little heat but not anything I'd ever be concerned over...the back up is keep as loose as possible while u are in the act of rappel and then u slowly apply the load the the backup when u need to stop and go "hands free"....so it is easy to get to break free again...the MM and back up hitch are sharing the load so not difficult to break the backup free again
