No problem to rope solo it with a 10mm or bigger rope on a gri gri and back up knot. Ok gear, boulder and small "tree" for ground anchor. Take a tag line so you can rap on it.
I'm off a few days next week. I've been eyeing that up and we should do it for sure. I have some nice small gear. might have to start up the first bit of Odin and traverse left. I couldn't see a good start, but could be wrong.
Heni and I did a line up to the right of Loki's... scary... hooking above shallow knifeblades and a section I had to free a couple moves... I was sweating.
