In reply to ksjs: As you live in Maghull I'll suggest some Welsh stuff:
Foil (Cromlech) as mentioned is pure class.
Stroll On (Grochan) is not far behind in the quality stakes, amazing.
Strike (Upper Tier, Gogarth) has been E4, either harder E3 or soft E4 I guess but straightforward if you're fit, very good too.
Sai Dancing (Holyhead) is superb with a tricky move right across the wall high up and then a weird and very trad pod / niche thing to finish.
Geireagle (Tremadog) is brilliant, I think some might say soft but I thought it was quite committing. I have the feeling that it's not quite as safe as the amount of gear available / peg suggest however.
Pen Trwyn has some superb E3s that fit the bill and there's a trio beside each other that are very much worth a visit: Klondike, Pocket City and Solid Gold. I thought Pocket City was the hardest of these and nudging E4 but good gear. All give great climbing (a few years since I did Klondike and I think Paul Williams suggests this is committing but I don't remember that).
If you haven't, Wilton is worth a visit; Supercrack was an early E3 for me so probably not hard but I have a feeling I'd still find it tricky. Max too is ace though this wasn't particularly hard E3.
Enjoy!
