Alexander Feichter has done the FA of The Darkness (9a) in Drittlsond, which is an easier variation of The Lord of Darkness (9b) he did in 2022, but which has not been reported. "Crazy powerful Line! Starting with a really nice crack continuing with the big roof of the Witch!"

What is interesting is that Alexander often projects his routes rope solo and actually often also sends them in this style. "I'm doing it because it makes fun and I really like climbing when my head says let's go. If not every time someone has time to belay you can climb and be safe. Also in the mountains, it is useful if some crux sections are and you need to belay if you are alone. Maybe well known by alpinists. Most of the time I get belayed by others. On big projects sometimes you are alone."

What kind of rope solo system do you use?
You make a fixed point in the other end of the rope and fix it in the first bolt in the bottom. Then you make 2-3 fixed knots in karabiners which you wear on a climbing harness and hang them in the boltes. The distances you have to calculate before or testing it. You can combine it with the Grigri, for the upper part, you can really quickly climb. Demonstrating Vimeo video.
