The Copper John Nymph created by John Barr is an extremely effective pattern for both Mayfly and Stonefly Nymphs. Here we use a two color wire technique and turn it into a soft hackle. Bead head soft hackle nymphs have proven to be the most effective patterns in our box time and time again. Check out the materials list here https://lelandfly.com/blogs/leland/bead-head-copper-john-soft-hackle-nymph. With this in mind we've created our own distinct adaptation of this pattern with extremely effective results, and a wide array of color combos.
