In reply to higherclimbingwales, jezb1 and Bradders:
Thanks all for your comments. They are really helpful.
jezb1: I had a navigation workshop with Paul Poole and I agree, he is a really good trainer.
As I'm based in Sheffield, I was looking at this provider called Peak Mountain Training, based in the Peak District. Has anyone had any course with them and would like to share their opinion?
Thanks again!
