In reply to Stig:
I love Gogarth and E3 is a great grade
Moon is a great trip an easy for E3
Sun at Roscollyn is correctly (IMHO down to E2, but still a fantastic route)
Rat Race is another soft touch at E3
The routes mentioned on North Stack wall really need a spring low tide as opposed to a normal low tide. However Blue Peter as E4 would get E3 (but poorly protected) at many crags and is at the less tidal end of the crag
T Rex is superb, E4 in the morning, E3 on a sunny afternoon
Nobody mentioned The Assasin, superb and reasonable pro, check out Syringe near by, superb but a bit rickety in places. Needle is good but maybe a bit of an eliminate
Sai Dancing on HM is also an excellent pitch
Kalahari is (IMHO) better than The Moon, albeit more seroios on account of the age of the pegs
I could go on and on and on
