Steelhead Intruder Leech, Pink

This pattern came from Grabflies "King Intruder Leech, Red" but I have only fished it for Winter Steelhead. In off color rivers like the Hoh river on the Olympic Peninsula. My first try with this fly I caught two Steelhead and no other flies were producing any results. I used a four inch King Intruder Leech, Pink on the Hoh, but clearer water rivers I use the three inch size.
