Well if I climb up to set it I like a running bowline w/a wrap, so it won't cinch tight, however if I want to triangulate because there's nothing in the center of the tree to tie on to. Because the tree whys in 2 directions, I put the rope through two equal crotches and tie a bowline w/a stick in it so it won't cinch. If it does, break the stick now you've slack to work with. However if you use throw bag to set it high, use a long rope once through the crotch take the end coming down. Wrap it around the trunk making a Marline half hitch and finish w/a timber hitch above the notch.
