The crazy thing about this is you’re all-in. There is no climbing down, especially after one of those leaps. The only way off the climb is up. Balsy.
A climber I was with did roped solos.
We were doing roped free climbing, but for practice he would lead the crux move part way, then reverse it, then finish.
Down climbing is often more difficult and it is possible to get stuck, not being able to yoyo for the gear.
No dynamic moves (leaps), intensely smooth up and down.
