Today was my first full day experience using furled leaders. Unless I was doing something wrong ( fishing), I am not to be a fan of same. After about 200-300 casts,the leader was twisting itself into little braids along it's length. At first the "braids" were easy enough to straighten just by gentle pulling on the leader but then as more braids formed, I gave up. All ended up in a tangled mess of leader, tippet and fly. By the way, the leader material was thread.
At this point, I'll have to say, NO furled leaders for me.
