I’m not a fan of loops, whether braided, built into the line, or hand tied. They add bulk, form hinges, are not aerodynamic, spray water, come off and don’t convey energy efficiently.
Some anglers use tiny spikes with built in loops
In addition to all of the above disadvantages, looped nails provide an unreliable connection and reduce buoyancy.
In addition to the above problems, leader buttons get caught on the rod guides
A solution to the above tribulations is Don Douple's Knot..
When I was a lad, my Dad told me “characters” are the condiments of life.
Don Douple is near the top of the spice rack.
I’ve fished with most of fly fishing’s big names. Don Douple is near the top of the list and THE best Pennsylvania trout fisherman.
Don trained as a teacher, but when he was student teaching, he discovered that he disliked the classroom. He became a full time student of wild trout and the waters they swim in. His knowledge and ability are unsurpassed.
Don’s attention to detail is intense. It plays out in his creation of the Douple Knot.
To create his knot Don mixes a little pigment from model paint with epoxy and forms an epoxy football over a Nail Knot.
This assures smooth passage through the rod guides while forming a strike indicator.
Point to remember
Don’s knot kills many birds with one stone.
