Anyone used 5mm titan rope for rappelling? (Tensile Strength: 3,100 lbf. (13.7 kN)). Thinking I might pick up some and give it a try. As I rappel using a figure 8, any size rope will work. With the goal of shaving weight and making every ounce count, thinking this might be a good way to cut down on some bulk (currently using 10mm rope).
Ran across this which makes me think why not: https://www.summitpost.org/phpBB3/how-do-rappel-off-very-thin-rope-t66735.html
I imagine that below 8mm, rappelling starts to become less fun. The friction on your hand will increase a lot. It will be much harder to control the descent. It will be harder to find prusik cord, which is a good idea to back up the fig8.
