I have been using the Abraded flat leader for 25 years, It's made out of one strand of 0.60 monofilament , Abraded in to the right taper. It has all the pros of a braided leader, just stretch mutch better because it's flat, is also cheap, and fast to make.
I dont really know for sure who invented this leader? it was shown to me by The now dead, Danish Fly fisherman and casting guro Ken Milton in 1983, I have used it ever since.
