Big up Dumby Dave! Looks like a good line (for Dumby!) in the second photo on the blog.
Now, I'm a bit confused about the potential Perfect Crime / Sanction link....I thought PC started in pretty much the same place as S, and traversed the roof low and rightwards to gain the arete beneath Good Nicks. Would the proposed link be reversing PC from some starting point on the right??
I wonder if there's a line direct through the W C graffiti too?
