Here's another photo from my caving trip a couple of weeks ago. Jimmy Williamson took it as I was climbing the rope on mechanical ascenders to get out of Hidden Cave. "Jugging" up a rope is a pretty strenuous exercise no matter what technique one uses, but we use the "frog" setup, employing one handled ascender, attached to a foot loop (with a safety line attached to the harness), in tandem with a non-handled ascender, attached directly to the harness and held flat against the chest by an improvised "chest harness." The "frog" setup is a simple but efficient system -- read more about it here: http://en.wikipedia.org/wiki/Single_Rope_Technique.
