I have a thread leader I have used so often tht it frayed in a several places. I mean really major frays. So I tied a loop above the frays and removed the damaged section. What I have is a leader about three feet in length and you know what? It turns over and fishes just fine. Love the furled leaders. I use a couple monofilament furled leaders but when I lift them they carry a lot of water. I expect it is my style that does this, but I prefer threaded leaders anyway.
