This is our take-off of the great RS2 emerging mayfly pattern developed by Rim Chung (RS2 stands for "Rim's Semblance #2"). We find that this version of the RS2 works well throughout the summer and into the fall, especially when fishing for picky trout in clearer water. Though the original pattern is tied without a bead, this bead-head version is great for faster water and as a dropper in a dry-dropper rig. Available in size 14, 16 and 18.
