In reply to GingerBread22: From my 50 best HS climbs in the UK list:
Main Wall HS 4b *** Cyrn Las
Dives/Better Things HS 4b *** Dinas Cromlech
Direct Route HS *** Glyder Fach
Manx Wall HS 4b *** Clogwyn Du Ymhen Y Glyder
Christmas Curry/Micah Eliminate HS 4a *** Craig Bwlch y Moch
Creagh Dhu Wall HS 4b *** Craig y Castell
The White Streak/Honeysuckle Corner HS 4a,4b ** Craig Yr Wrysgan
The Cracks HS 4c *** Dinas Mot
Pinnacle Wall HS ** Craig Yr Ysfa
I personally also really rated Jingling Wall HS 4b *** on Clogwyn Cyrau above Betwys y Coed, Conwy Corner S *** also looks good there.
