In reply to diddler:
This is just a reply in the absence of better info as I haven't been yet this year. However my suspicion is that it will not be in the best condition as yet, particularly in the areas where the 7b and above routes are. The crag gets a bit dirty with a kind of powder lichen that can hold moisture. There are a couple of quality 7a's that get done more and are most likely to be clean...Clink and Distant Lands, and in the same area is Pimp with a Limp at 7a+. Good luck if you do go.
