Why the 20 incher fly pattern belongs in your own fly box
If you've spent much time nymphing deep works, you've probably heard someone rave regarding the 20 incher fly pattern . It's one of those flies that just looks like "fish food" the time you see it within a fly package. There's no nice foam or high-tech synthetic flash—just a whole lot of peacock herl and pheasant tail that will appears to drive trout absolutely crazy. I remember the 1st time We tied one upon; I was a bit skeptical because it looked a little bit like an untidy version of a Prince Nymph, yet three casts into a fast riffle, a solid brownish trout proved myself wrong.
The beauty of this fly is the fact that it's not trying to be a specific bug, yet this manages to appear like everything at once. Is it a big stonefly? Is usually it a beefy Mayfly nymph? Honestly, the fish don't seem to value the taxonomy as much as we do. These people just see a heavy, buggy user profile tumbling along the particular bottom and choose it's worth a bite.
The particular story behind the particular fly
We all can't really talk about the 20 incher fly pattern without giving a nod to the creator, Charlie Craven. If you know anything about fly tying, you understand Steve is an expert of creating patterns which are both extremely effective and relatively easy to mass-produce at the vise. He originally designed this fly to be a "confidence fly" intended for big water, especially in the Western world where stoneflies are usually a staple of a trout's diet.
The name itself is of the challenge. It's known as the 20 incher because, well, it's supposed to help you land fish that hit that magical twenty-inch mark. It's a strong claim, however the fly usually backs this up. It offers ideal combination associated with weight, silhouette, and movement that creates an aggressive strike through larger, more territorial fish that aren't interested in small midges.
Why is it so efficient?
You might wonder why the bunch of feathers wrapped around a hook works much better than some of the more modern, "realistic" styles. The secret sauce from the 20 incher fly pattern certainly is the peacock herl. If there's one particular material that provides caught more fish than some other in the history associated with fly fishing, it's peacock herl. It has this organic iridescence that shows light in a way that appears like the trapped air bubbles or maybe the metallic sheen of the real insect's exoskeleton.
Then you have the pheasant end fibers. These are used for the tail, the wing case, and the legs. Pheasant end is naturally mottled, giving the fly a lifelike, segmented look. When you combine the twinkling green from the herl with the earthy browns of the pheasant tail, a person get a fly that stands out in murky drinking water but nevertheless looks organic in clear mountain streams. It's the particular ultimate crossover nymph.
Tying the 20 incher fly pattern
When you're seated at your vise to tie some of these up, you'll find it's the pretty satisfying procedure. You'll want the 3XL long nymph hook because this particular is a large bug. Most individuals start with a silver bead head—tungsten is better in case you actually want to obtain deep—and then add some lead or lead-free wire wraps behind the bead. You want this particular fly to sink like a rock.
For the particular tail, you're making use of pheasant tail fibres. Then comes the particular ribbing; I go with fine platinum wire to provide it some extra flash and to guard the delicate peacock herl in the the teeth of hungry trout. After you've secured the wire, a person wrap a heavy bunch of peacock herl forward to produce a chunky, segmented entire body.
The "wing case" is simply more pheasant end pulled over the best of the torso. The trick to making the 20 incher fly pattern look actually "buggy" is within the legs. You consider those same pheasant tail fibers plus fold them back along the sides. It gives the fly a wide profile that generates a lot associated with vibration in the particular water. I like to finish mine with a little little bit of dubbing directly behind the bead to cover the thread wraps, usually in a dark brown or black.
How to fish around it properly
This isn't the fly you want to fish on the light 2-weight pole with a sensitive presentation. The 20 incher fly pattern is a heavy hitter. Many of the period, I'm fishing it as the prospect fly in a two-nymph rig. Because it's so weighty, it acts as a good anchor, pulling your own smaller dropper fly down into the strike zone considerably faster.
You want to fish this deep. In case you aren't occasionally ticking the particular bottom and shedding a fly to some submerged log, you're probably not angling it deep plenty of. I use a strike indicator and adjust it so the fly will be drifting just ins above the riverbed. In faster drinking water, don't be afraid to include a little bit of split chance a foot approximately above the fly to make certain it doesn't simply sweep within the heads of the seafood.
Another great method to fish this is with a "dead drift and swing" technique. Allow the fly drift naturally through the head of a pool, and since it reaches the end of the move, let the range tighten and permit the fly in order to swing toward the particular bank. Sometimes, that sudden change within direction and the particular way the pheasant tail legs flutter in the current is exactly exactly what it takes to trigger a strike from a big trout that's already been watching it the whole time.
When in case you achieve for it?
While you may fish the 20 incher fly pattern year-round, this really shines throughout the spring and early summer when stoneflies are energetic. When the drinking water is a little high plus off-color from snowmelt or rain, the particular dark, chunky figure of this fly is easy for fish to spot.
It's also the fantastic "searcher" pattern. If you're upon a new item of water and there's no obvious hatch happening, tossing a 20 incher into the deepest, darkest holes is usually a great method to see who's home. It's large plenty of to be a meal, but not therefore intimidating that a smaller trout won't take a crack with it too. I've caught everything through six-inch brookies to twenty-plus-inch rainbows upon this thing, frequently in the same stretch of water.
Variations to bear in mind
Like any kind of classic, people have tweaked the 20 incher fly pattern over the years. Several people like in order to work with a silver bead instead of gold, or even a coloured bead like orange colored or red to do something as a "hot spot. " I've seen some versions tied with a bit of flashabou over the side case for extra visibility in muddy water.
If you find that the standard size is a little bit too big with regard to your local creek, you can always scale it straight down to a size 14 or sixteen. In those smaller sizes, it starts to look more like a dark Mayfly nymph or the caddis larva. Yet honestly, there's something special in regards to the original size 8 or 10. It's a fly with presence. It says, "I'm a big pest, come and obtain me. "
Conclusions on this particular classic nymph
At the finish of the day time, fly fishing is definitely often about confidence. If you believe a fly will probably catch fish, you'll probably fish it better—you'll be even more centered on your drift, more attentive to your indicator, plus quicker for the lift set. For me personally, the 20 incher fly pattern is definitely one of those flies I may always rely on. It's been a basic piece in my container for years, plus it's earned the spot through numerous successful days upon the water.
If you haven't tried tying or even fishing one yet, give it a shot. It might look a very little old-school in comparison to some of the fancy new patterns striking the fly store bins lately, yet there's a reason it hasn't gone out of style. This just works. Whether you're targeting that will trophy trout of the lifetime or just want to have a productive afternoon on your own favorite tailwater, you really can't fail with this buggy masterpiece. Just make sure you provide a few extras—once the fish start hitting them, a person won't want to run out.
