In reply to crispy:
most use full thing would be a static 10mm for setting up anchors but also a full rack wouldnt go a miss, better of heading to sheeps tor on dartmoor moor accesible and less kit needed, good selection of routes from severe up to E1 loads of good anchors:
selection of slings and krabs if you dont mind sitting at the top, and again a lead rack would be usefull if not large metal hexes or nuts would help.
