Have you got the CC Cloggy guide? It has a list of routes that dry quickly if I remember rightly, can't think of them off the top of my head at work. Anyone else got a copy to hand?
In reply to Owen W-G: According to my cloggy guide Scorpio should dry in one good day (imagine pinnacle arête would be similar) and shrike takes 2-3 days of good weather. Great Bow I would imagine takes a little longer again.
