A concoction I came up with prior to leaving for the Bighorn one spring for the olive hatches that we were to fish. I wanted something a bit different than the norm, and it worked very well. I came back to lowly Connecticut and transposed this recipe into all of my surface emerging mayflies with resounding success. If the trout were tough, they couldn't refuse this fly. Tie em in all the colors and sizes to imitate your prevailing mayfly hatch. Good luck and happy tying.
