I fish Zen Outfitters furled leaders almost exclusively. I buy them in the 78in length and add about four feet of nylon tippet. He also has a big streamer leader and a sinking leader both of which I like very well. I also have a Moonlite Flies leader that I like but I have to dress it with Otter Butter so it will float, which is no big deal. I do prefer thread leaders over any other material they are softer give a good hook set and lay the dry fly on the water very easily.
