"One of my top 5 nymphs anywhere I fish. I first used it in the Czech Republic at the World Fly Fishing Championships in 2014. It was immediately successful on my local trout streams when I brought it home and it has continued to work just about everywhere I fish. It has a more "pulling power" than imitative nymphs and it catches fish when they aren't on the feed or willing to move far. Try it in your local trout stream and see how they work for you!" - Devin
