The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
I thought Letort was in PA
Why would you want to use a specialized leader that is designed for delicate presentations of dry flies when you are high sticking with most of the line and much of the leader off the surface of the water. BTW I got all excited about the furled leaders back when they were buzzing in the magazines about 6 - 8 years ago. I bought a couple and didn't think they were anything special. I could already throw a WF#4 40' with just a couple false casts and 50' with two hauls so didn't see the sense of spending 5X the cost of a good tapered leader.
