In reply to johnl:
For the culm coast, get to Blackchurch. Plenty of non-tidal stuff on the main cliff there if you like that sort of thing. Personally I've only done Loose Women, but that was magnificent. You could take a belay on the ab rope for stuff on Blackchurh Rock too I guess.
I think Hippa Rock near Lower Sharpnose is also non tidal, but could be wrong?
I think you mean high spring tides by the way (when the moon is near full). There should be plenty of manageable stuff accross much of the culm on a high neap (weak) tide. So don't get put off if someone tells you it's a high neap, although the last few days have seen spring tides.
