I recently started indoor rock climbing at a local spot. I got to the top and (after appropriate communication) my partner started to belay me down. I instantly starting swinging and spinning pretty wildly, more than 10' arcs. I was able to catch the wall, but every time I let go the same thing would happen. I didn't see anyone else having this problem.
How does one descend in a relatively vertical fashion without swinging like a pendulum?
