I make them as well. I guess mine are all over the globe these days. I have caught hundreds of Carp this year all on one thread leader. Night thing about the thread, you can put floatant on them to fish dries, or just squish it underwater and it becomes a great Nymph/streamer line. However, thread will freeze to rocks in the winter, so that is when I switch to a special mono I use. I am not one that believes in a Fluorocarbon leader. Finding fluoro small enough to make a nice soft leader is limited, plus costy. I swear by fluorocarbon however. I just choose to use a 5' thread or mono leader with 3' to 5' of fluoro tippet. Works for me.
