This fly was named after the dangerous drink called the Micky, as this is a very dangerous streamer to Trout, Salmon, Bass, etc. The colors of this fly (red, yellow and silver) make this fly attract the fish and drug them. There are many different variations of this fly and Region tries to stay true to form of the original Micky Finn. Put a couple of these in your box so you can drug that big Brown, Rainbow, Salmon or Steelhead. This might turn out to be one of your favorite streamers to fish as it is one of ours. All streamers or lead weighted to get your fly into the water column quickly.
