Thanks James. It only looks fluid because I've tried it so many times and so had it pretty wired in the end. I now am not 100% sure if it is actually quite hard or I was being a muppet.
The problem climbs really nicely (I'm totally biased), a good combination and variety of technical and powerful moves.
(If anyone wants a little tour up there, let me know and I'll do my best to come out - provisos regarding kids/work/life etc etc as I struggle to get out much myself.)
