In reply to MikeR:
I would second the suggestion of Scabbard as it is fantastic, but probably just the first two pitches to the ab spike as I doubt the top third and descent would be much fun if wet... While you're in there, although HS, Talisman could be worth a look but I doubt the first pitch dries fast. The top two pitches however are more exposed on the arete so should dry fairly quick.
