Yesterday was my first experience using a furled leader. I was using it on a bass bug line. Overall it worked well for me. It seems to lay out the fly better than store bought tapered leaders. Late in the afternoon I noticed the furled leader was getting twisted up signicantly and knotted. Most likely due to my casting as regular leaders often get snarled into a bird's nest. Is a swivel recommended on the tippet ring at the end of the leader? Other suggestions are welcome.
