Thanks for the info, I did figure they had all been climbed before just thought I'd have ask around as they were really nice problems in an area I'd never heard of for having bouldering before. The second problem is definitely worth a seeking out, with some quite powerful moves up the twin overhanging cracks and lip of the arete. It's basically the first piece of rock you meet on the way down to the crag.
I also had a look on the tors up on the hill on the other side of the main road, is there anything up here? There looked to be a decent, quite holdless, hanging prow that would have yielded a good problem but the landing was terrible and I didn't have a mat so skipped it.
