This is what I said in the other thread.
World Wall 2 is almost always dry and I am not talking about kinda dry in the rain. I was out there a day it rained an inch and webelo, Bones and Drill were all dry still. Renaissance side is probably mostly dry with the wettest route being the start of orgasmo. Chronic and Californicator are also both almost permanently dry. It is cold as hell on the actual rock.
By grade what I think is dry: Reptiles 5.9, Jug or Not 10b, Goddess 10c, Abo 11b, Rainy Day 12a, Lay of the Land 12a, Californicator 12d. You will probably get the screaming barfies the rock is insanely cold, I just have spent the winter training in my non insulated shed so I am quite used to it.
I personally wouldn't try to regularly try to get most your training outside at little si unless you are projecting 12d or harder. The only truly permanently dry routes are Chronic, Californicator, Webelo, Bones, and Drill Sergeant. I have taken some pretty large whippers off techno and hydro because of wet holds and not been able to climb prop and pyscho due to seepyness.
