I would like to semi permanently belay stuff while rigging but still be able to undo it to re-tension at a later time if need be. I'm finding that when I'm rigging a line, stuff that I have already done has gone slack and there is a good chance of getting the new line on the wrong side of the existing ones. I tried small alligator clips but they want to slip or fall off. Some kind of quick drying but very easy to undo glue might work. Anyone have a solution to this problem?
