With my interests turning once more to just getting climbing rather than specifically seeking virgin geology here is a reluctant offering from my stash.
The Marchlyn slopes (sh608 621)
Would suit a pair of fell runners as a good spot is more important than a pad. I succeeded on the left arête from a sitter to top out(F6C?). However, the full traverse is up for grabs. Likewise did a number of standing straight ups (upto F6B?), but the sitters are all nails. Really nice piece of rock, and would already be a classic if near the road.
