I love Interstice. To me the climbing is varied and very fun. I think the first pitch is 10b and the second pitch roof is harder at 10d (this is how Dick has it written and it seems right on to me).. . I never thought of it as being to run out, I've always thought of it as PG (a little heading a a spot or two but not even close to R). The second pitch roof is awesome, I don't want to give away any unwanted gear beta but it's there, strenuous to place but there. Dick says there's a 9R section here but I never really found that to be the case… Combining both pitches in one is a whole lot of rock climbing in one long pitch.. Super fun…
