I recall a while back that Luke Laeser and another strong climber did something like 64 pitches in a day there. American Dankster and I are aiming to do a 20 pitch day there when I come back home for Christmas. Any of you have experience knocking out big double digit pitches there? How many did you get in?
I don't know what the max number of pitches I've done at Twall in a day might be, but i've found it pretty casual to get in 10 or so as long as you don't have any specific routes in mind and just get on whatever is open.
