This my be an old question to some but one that I've been dwelling on for awhile. In my arborist work I've used DbRT to climb and move around around the tree (limb walking) The friction hitch provides comfortable tension to safely move around. In Search and rescue, caving and cayoneering I've used the Single rope techniques and mechanical advantages because these are somewhat linear activities (up and down). What I'd like to know is how you move around the tree using SRT. Or is this just a way to get up the tree. Also any good suggestions for securing the rope to the branch (like a running bowline or ???...) Any good reading or video for SRT specific to tree climbing.
