Damn right! There's a load of problems described in your grade range in the BMC Roaches guide i.e Peace of Mind Boulders, Lower Tier + Upper Tier Boulders. When you've exhausted them, Doxey's Pool and Skyline Boulders are also a great place to visit with loads to go at. There is a guide called 'High Over Buxton' too which you might get from Jo Royle in Buxton, this covers a load of esoteric areas too in the Three Shires Head region, and if the Limestone sections are avoided, is actualy worth having.
Get to it!
