Hi JP, it was connected to the braided loop, I was fishing a straight 14ft, 4lb leader. I know I will get far better T/O with a tapered or furled leader, especially with small flies, but if you want an honest answer, that was what I was doing and that is where the knot failed. As I think I said to begin with, I really like this knot, it's simple and neat and I can get a smaller loop than fig of 8 allows (well at least with my fingers!). I will give it another go with the 6lb. Will also make a furled leader or two!
