I feel the same. Nail Knot is always been my choice as far as knots go, for smoothness. But, alas, I too have been furled leaders for a very long time and only knot is in the tippet. I did have a molded loop fray yesterday while trying to land a carp. Made for a difficult land and a bit scary when the leader wrapped around the tip as I tried to get the loop through the tip top. All worked out though
