I've been fishing this little nymph for a few years now. I like it in small sizes like 18's and 20's. Being a small fly without appendages gets it down quick and the profile is perfect for those small mayfly nymphs that fish seem to target more often then a larger offering. Give this little power house a go. I think you will be pleased with the results. Fishes great under a dry fly or as a dropper on your euro rig.
