In reply to the cassin ridge: i havent done much there but:
HVS - Britomartis and King Bee Crack (assuming im allowed Holyhead). not sure if you can get a better position on an HVS than you do with Britomartis, one of my first HVS leads and i can remember so clearly traversing away from the belay with the sea to my back and an expanse of wall above waiting for me...
E1 - Emulator and Breaking the Barrier. Emulator is high quality E1 with great variety, it keeps coming
E2 - think it has to be The Strand though again if we think about Holyhead, Bran Flake is ace
E3 - i start to run out of experience here as the only E3s ive done have been on Holyhead. if however you give Strike E3 i think this is brilliant but it really suits my style, arguably just worth E4. Sai Dancing is superb as is The Final Solution (previously Penny), think Sai Dancing's crux could be 6b. ive been looking keenly at the crack line left of The Cruise on recent visits, havent done it but it looks really good: Who was HB?
E4 - Katana (now Penny) is class - sustained but never desperate with good gear and, though not an amazing line or anything, Snakebite Wall is cool if you like that sort of thing: crimpy, open wall climbing. this was E5 but has gone down, correctly i think, to E4 in new Gogarth North
E5 - Run Fast Run Free. this was to be my first E5 but i got to the pod and decided it was too damp so came down
anyway, what i did was quality and the top section looks brilliant. maybe this winter if we get some sunny days...
