“I was fishing one of my favorite lakes in high mountain south central Utah lake. Fish were feeding all over the place. None of the usual patterns were producing. I put this fly on in a size 20 olive. The final 30 minutes of fishing light were fast a furious. It also brought over several fellow anglers to see what I was throwing. I passed out a few to some of the guys. They started catching as well. It wasn't me, it was the fly. Will never hit this or any lake in the area without several of these in my box”
