Please refer to the profile. This is a 3.5mm tungsten bead head keel nymph. It's slim and sinks easily, and the keel shape makes it less likely to snag. It's perfect for deep water and sight fishing with tenkara outrigger nymphs, as an anchor lead fly in a trailer-style double nymph rig in fast currents, and for down-and-across euro nymphing. (For regular loose nymphing, a nymph with more bulk and drag, like an MSC, might be better.) You can get a discount by using the "bulk purchase request" option, so please inquire. Light nymphs are difficult in general mountain streams, so heavier ones are easier to start with. How about using it for bait, tenkara, outrigger nymphing, or other fishing methods where you fish directly below the rod tip? Thank you for your consideration. #flyfishing #finishedfly #nymph
