In reply to Ed morris:
I can recommend you have a look at Pen Olver. We spent a day there last year and it's a very pleasant crag. There's quite a few climbs in the grade range you're looking for and the approach doesn't require an abseil (although it took us a while to find!).
We also popped into Trewavas on our Cornwall trip this year and that's probably worth a look. Check the ukc crag search for some more adventurous suggestions, if that's what you're looking for.
