In reply to Slimneck:
I do slightly find this true, as I like to know what the grades are of the problems I'm climbing. However at the arch, I am really enjoying the circuits lately and like the idea of them; not knowing the exact grade but the approximate grade range.
At the biscuit factory I almost solely use the comp wall. It has individually graded problems which I like and the setting seems to be much better.
At the arch, before the biscuit factory was there, there were a lot of individually graded problems and I don't see why they now need to switch to circuits. I much preferred it the old way. Saying that I still don't much mind the circuits.
