In reply to Chris Aston:
There are a few routes at the all weather gym at hodge close that stay dry, I wouldn't make a long drive for them though. Bouldering at minus 10 and raven tor probably dry but tbh very little in your grade range if anything. Ever done any aid? Thors cave or some of the dovedale routes are fun. We learnt to aid on them as all the gear in insitu, just need to buy some etriers and daisychains each and your away!
