The Single MinnowFly is approx.. 1" ;3/4” long. It has a soft body so it accepts a scent readily. You can use it in 3 ways. If trolling, attach the fly 9” to 12” behind a slow trolled Dodger. 1-1&1/2 mph. If spin casting, use a long leader and a weighted casting bobber. If fly fishing, use a medium or fast sinking line and leader. Retrieve it as a streamer.
