There's only 3 patterns that I developed that many anglers have used with good success. This one is responsible for at least half of the fish I catch in stillwaters. I call it a Turbo Leech because it is so fast to tie. I tie it in a number of colors but olive and brown seem to produce the most trout for me. I'm showing a burgundy color because it also works from time to time and the color is prettier than olive or brown Black is another producing color as is yellow... so is chartreuse. Sooooo, I tie them up in a number of sizes and colors. Afterall, they are fast to tie so I can cover a lot of bases. During damselfly hatches, a size 12 olive color Turbo Leech with a gold bead head normally works better for me than more realistic looking damselfly nymph patterns. Materials: Hook: Spear-It N063 or similar 3X long wet fly hook, sizes 4-10 Bead: Gold or silver Thread: 8/0 black or match fly color Rib: Copper, gold, silver or red wire (normally I use copper for all my Turbo Leech patterns but I used red for this one) Tail/Body: Blood quill marabou Step 1: Install a bead and clamp the hook in the vise Step 2: Attach a length of wire and over-wrap the hook shank, stop above the hook barb Step 3: Tie in a single marabou feather so the tail extends about the length of the hook, make sure the wraps are tight Step 4: Run the thread forward to the bead. Twist the marabou into a rope and wind forward to the bead (option: twist the wire rib in with the marabou, in either case, the rib is meant to add a bit of durability to the marabou) Final: Whip-finish and you're done You'll find that I'll mention a Turbo Leech pattern quite often when talking about stillwater patterns. Now you know what I'm talking about.
