Ahh yes,
I remember doing that Bloodscream arete at some point last year, it's quality.
If you can be arsed to walk up to Y Foel Penol (SP?), also in the CC guide, there's some worthwhile traversing and up problems on the wall behind the main crag.
Purrfection (E1 5a) is a good highball and there are a few good short routes to boot.
Worth the trip IMO
