Copper John was designed by the John Barr from America and like many other flies through time, it was named in the head of the author.
This very heavy Copper John variation comes with 3.8mm metallic purple tungsten bead and green/black rubberlegs.
This one is perfect for streamwater sea trout fishing when you need to get the fly down into the deep pools right away! It has been very effective in the sea trout rivers of south Iceland.
