So far I've just been sticking to the white trails (easiest) up the walls and have been doing ok. Some of the more experienced people are pretty damn good. It'll take me quite awhile to get to their level if at all. The most painful part of the whole climbing experience isn't the climbing itself, but dealing with the equipment. Getting into the harness is a pain the ass and if you're not careful with the latches on the clamps you can constantly give yourself really painful pinches on your fingers.
