so i understand that fliplines are to hold you in position in the tree, but do they have other ways to be used than just around the tree right in front of you like when using spikes? reason i ask is that is seems they wouldnt sell them in lengths of like 18ft if they were just to use around a tree right in front of you unless you would be climbing a tree about 5 ft in dia, so i wonded are they also used to move around in the tree, like anchor to a crotch above you and with 8 ft of loop out you could move around some yet stull be securely hung in place? kinda like ya do with the loop of rope in double rope climbing. or are thse long lengths just for big trees. also is the term lanyard and flipline interchangable or is there a difference in use or construction? right now i often use a length of rope that i can clip around and back to my harness to keep me from falling outa the tree, actualy i have two so i can stay attached even as i move around stuff. was kinda thinking i liked the safety of a wire core flipline but not sure of there use and limitations exactly
