In reply to alastairmac:
I've been there twice, last time about 2 years ago. It is an immense place with many crags and, as you noted, with new ones being developed all the time, so I've only barely scratched the surface. However from what I have done and seen, we all felt the grades there to definitely be on the harsh side, and don't recall all that many below 5--though, given the nature of the area, I guess there could be entire crags full of 4s that I don't recall. For a good selection of climbs at that level, and a bit friendlier grading, have you considered San Vito on Sicily?
