Thanx Ross. That’s an answer I was looking for; nice and technical.
At the moment Bluff Knoll doesn’t call me. I will just be climbing around Churchman’s Brook via topropes for a while. The idea is whilst on the toprope I want to start learning to make good placements with passive pro initially, while I build up some more experience before doing a lead course and going on the pointy end. Baby steps!
