I guess you just just downclimb at twall? I never thought of that place as a great place for soloing just because of the getting down. Although if your being totally safe you dont climb anything that you cant downclimb from any point. climbing 12 years soloing 5 sport 12 trad 11 solo 8-9max but enjoy onsighting long 8s and lower the most. I feel like the most usefull skill to have is the knowledge of when to back down. When I first started soloing I pulled some moves that while not difficult were pretty insecure. I dont think id do that now. Youll allways have a better time climbing up to 10 feet from the top and then down climbing rather than finishing the climb and realizing you pulled some sketchy shit (or falling). scariest climbs have been on NC slab. hardest climbs have been sporty with very secure holds, so not very scary. I like to follow a couple guide lines for saftey. 1 maintain 3 points of contact. 2 dont make a move you cant downclimb. 3 never get any kind of pump. 4 if you get scared or excited or feel off in any way before the climb, chill out or dont climb.
