The Mushmouth Series

By David W. Skok (2004)

I’m not sure how much time I spent at the vise the first fifteen years I tied flies, but I do know that it feels like I spent nearly that same amount of time unwrapping the wings and tails of fouled streamers while fishing.  Nothing makes me crazier than a fly whose materials just won’t stay where I put them.  I’ve even been known to throw a brand new fly overboard if it fouls more than once in every twenty casts or so.  You can picture it.  You just made a perfect cast and it should be a sure thing first strip, but the fly makes it all the way back with nary a nibble.  You’re dumbfounded.  What? Ah, it’s fouled.  This pain is felt particularly by shorebound fishermen who may wait a day for a chance at a fleeting false albacore blitz or a cruising twenty-pound striper, only to find that their only opportunity was blown by a disfigured bug.  The Mushmouth series is a quick and simple solution to this common streamer problem.

The Impetus

Chris Aubut and I first caught skipjack tuna with the Mushmouth.  Offshore fishermen sometimes refer to skipjacks as "mushmouths" or "mushies" as they will often fall off the hook when brought in on heavy tackle at trolling speed.  Chris called me a few Julys ago to clue me in on a skipjack bonanza that was going down around Newport, Rhode Island.  Skipjacks don’t usually appear in our Southern New England waters until sometime in August or early September (if they show at all) when the water temperature peaks.  The summer of 1999 was unusually warm, however, with most days finding the mercury over ninety degrees Fahrenheit.  Coincidentally, a large finger of warm Gulf Stream water had also pointed its way north straight towards Newport.  This highway of tropical water led the oceanic bonito and some small bluefin tuna to a nice, deep pocket of tepid water and an unusually large body of immature oceanic herring.  If this sounds like a saltwater flyrodder’s dream come true, then you’re half right:  the table was set and the bell was ringing, but we could hardly buy a bite to save our lives!  The oceanic herring were tiny – really tiny.  These baitfish were the length of a dime and only as thick as a matchstick!  On top of that, skipjack tuna often feed at the surface in fighter jet formation and “foam” when on small baits like these.  Foaming skippies (or other tuna – I have witnessed false albacore, school bluefin tuna and frigate mackerel feed this way) move in wide schools of ten to several hundred individuals, all moving in a singular direction at the same speed (fast!), essentially mowing down every baitfish in their path.  The combination of these truly minute baits and the skipjack’s propensity to feed in this unusual manner made for a tough bite to say the least.  Chris’ clients had taken fish on large, six-inch 3-D Fleyes made almost entirely of Flashabou on previous days, but they were slow to tie and not as effective as he had hoped.

The Concept

The Mushmouth Series of flies were all designed to be non-fouling, quick-to-tie baitfish and squid imitations.  The original version was made primarily of Angel Hair or Wing 'N Flash and since then innumerous variations have been created to match different baitfish with different materials.  Any non-tapered synthetic or natural material can be used.  Popular choices are Slinkyfibre, Unique Hair, Bozo Hair, PolyBear, Mega Mushy flash and natural yak hair.  Tiers will find that each material has its own distinct purpose as their length and denier vary.  As you might expect, longer and thicker fibers are best suited for big flies and shorter, finer fibers are best for smaller offerings.

The common element of all Mushmouth family members is a stiff, yet flexible spine of Super Hair and Softex or Soft Body Glue that extends past the hook bend.  This Super Hair / Softex spine keeps the fly from fouling during the cast.  It also helps the fly retain its profile when fished in fast current and protects it from becoming a one-fish wonder.  Only the Mushy Squid and the Whitebait Mushy deviate from this theme and in both cases another material was substituted for the Super Hair tail solely because those patterns warranted it.

Why so much glue?

We tied the first few Mushmouths without a spine or any glue in the dorsal area of the fly and they did catch fish, but they also wrapped and tangled like there was no tomorrow.  We brought the remaining flies home and coated them with epoxy to reduce fouling and we ended up with just about the worst looking Surf Candies the world had ever seen!  I figured there had to be an easier, quicker and cleaner way to make this fly worthwhile, so I went home and experimented and found that a spine of a one-part glue like Softex made the tying process a whole lot easier.

Don't worry that the fly may turn out too stiff.  Remember that there are always a zillion short, wispy strands of flash hanging out of the fly that wave in the current and provide the illusion of movement.  It is important, however, that you don’t make the tail extension from epoxy or extend it too far past the bend as this will keep striking fish from getting hooked.

A warning should be given about the toxicity of the preferred glues.  Softex is a one-part glue that contains numerous solvents that are considered toxic.  Solvents like those in Softex are absorbed primarily through the skin so tiers should wash their hands repeatedly during a lengthy tying session.  It is also important to use this glue in an area with adequate ventilation.  I tie next to a window with an exhaust fan that removes most, if not all, of the fumes from my tying room.  Tiers that would rather avoid Softex altogether are not without a substitute.  Soft Body glue by Angler’s Choice is also one-part, but is water-based and therefore does not contain the nasty solvents found in Softex.  Soft Body has an unusual non-chemical-like scent and evaporates at a much slower pace.  This slower evaporative rate means that your flies will take longer to set and Soft Body also provides a stiffer and clearer finish.

Some Tips On Tying

All of the different models of Mushmouths follow the same basic steps.  Keep in mind that the belly and back components of the fly must be tied in while the Softex is still wet.  The belly and back materials must therefore be prepared ahead of time so that they are tied in just moments after the glue has been applied to the Super Hair tail and the hook shank.  As a rule, the quicker you tie it, the nicer the fly looks when finished.

The most difficult portion of the tying procedure is learning how to handle the tying materials prior to tying them in.  The thinnest flashes like Angel Hair or Wing 'N Flash in the standard Mushmouth are the most difficult material to deal with.  These materials are simply finely shredded mylar tinsel that seem to be on a mission to make your entire home resemble a ‘70’s disco ball!  The easiest way to deal with this material is to first remove it from the zip tie and then create a layered bundle by realigning the fibers on a table.  Never cut any of this material with scissors.  The strands are fine and weak enough that you can pull out the necessary amount.  Pulling the material out of the bundle stretches the material just enough to create a frizzy texture that helps build bulk.  Creating a tapered bundle of flash is truly the key to tying this fly well.  A tapered bundle of mylar is made by pulling out the short fibers and tearing any undesirably long fibers and then repositioning them in your bobbin hand.  Repeating this action several times will build bulk in the tie-in area so that a tapered bundle is created.

Creating tapered bundles of other synthetics like Slinkyfibre or Unique Hair is much easier and can be accomplished by simply pulling out the center strands to longer lengths.  Most people find that Mushmouths made of Slinkyfibre are the easiest version to tie.  This truly is a technique where practice makes perfect.  Don't despair if your first attempts are not as nice looking as you had originally hoped, as they will still fish well and every fly looks good when lodged in the corner of a big fish's jaw!

Most of the Mushmouths you’ll tie will require a slight trimming at the end of the tying procedure to create a tapered, lifelike baitfish shape.  The easiest method to do this is by positioning the fly vertically in your vise so that the hook eye is pointing upward.  Trim the fly slowly (you can’t put it back on after you’ve chopped it off!) with a pair of long-bladed scissors, making your way upwards from the tail towards the hook eye.  Do this for both the belly and back areas until you are please with the final shape.  It’s important to have a good pair of serrated scissors with blades that measure at least 2 inches to trim the fly properly.  Your typical trout tying scissors are going to prove slow and cumbersome and usually leave you with a rough, blocky look to the body. 

'Tis the Season

Like any good pattern, the list of species taken on different Mushys is extensive.  Mushmouths are good all-around searching patterns but there are certain situations where they seem to excel.  The flashier varieties commonly get bites in tough situations where other flies fail.  Crab and krill hatches, dense schools of small bait and normally unaffected migratory fish are all situations where a flashy Mushy often has a better success rate than other approaches.  The Mushy has now fooled nearly every species of pelagic fish from bluefin tuna and frigate mackerel here in the Northeast to Baja mahi and roosterfish.  Friends have taken Costa Rican sailfish on giant tandem-hooked models and plenty of big stripers to thirty-five pounds have shown poor judgment when a twelve-inch Mega Mushy whizzed by.  There are times, however, when a flashy fly is the worst possible choice.  I have seen fish streak away from a flashy fly in fear on some days!  In particular, bigger striped bass seem to prefer less flash.  Switch to a more subdued Mushy made of Slinkyfibre or yak hair when overwhelming shine isn't the ticket.  On the other hand, jacks, bluefish and snook rarely pass up the chance to demolish a flashy version.  Other fly fishermen have reported similar success with larger freshwater predators like northern pike and lake-run salmonids.  Take five minutes to whip one up the next time you sit down to tie.  You’ll save at least that much time on the water when you don’t have to reach out to untangle a fouled fly every third cast!

-------------------------------------------------------------------------------------------------------------------

Step 1

Using clear monofilament thread and a #4 – 2/0 short shank hook, tie in a tail of white Super Hair mid-shank.  Make sure to taper the ends of the Super Hair by pulling the center strands out to longer lengths before tying it in.  Take one or two turns of thread under the tail to cock it up at a slight angle.

Step 2

Cut off six full-length strands of Flashabou and fold it in half and cut it so you have 12 strands of half-length Flashabou.  Stagger the ends of the flash and fold it in half.  With your thread just in front of the Super Hair tie-in point, hook the loop of Flashabou (formed by folding the flash in half) under the hook eye and tie down with the clear thread.  This should put equal amounts of flash of varying lengths on either side of the Super Hair tail.

Step 3

Prepare 2 bunches of Wing ‘N Flash, Angel Hair or Lite (Long) Brite for the body, a light color for the belly and a darker color for the back.  The two bunches should be prepared so that they are longer than the length of the tail plus about ¾” – 11/4”.  The bunches should be pre-tapered so that the thickest portion of the bunch is at the tie-in point (just in front of the Super Hair) and getting progressively thinner towards the tail.  The easiest method to achieve this taper is to PULL (not cut) the material from the hank and then deal with the material in your fingers.  Take any excess material and pull it from the bunch.  Realign this material in the area of the tie-in point.  Repeat until the necessary taper is acquired.  Additional material may be need to gain the proper thickness and taper.  Conversely, you may initially select too much material and need to remove some.  Practice is key.  Your first Mushmouths will probably look horrible, but fish well.  Most people find it much easier to produce a finished-looking fly after six or eight attempts.  Creating tapered bundles of other synthetics like Slinkyfibre or Unique Hair is done by simply pulling out the center strands to longer lengths.

It is critical that you prepare your Wing ‘N Flash bunches ahead of time as you want to tie them in while the Softex or Soft Body glue is still wet.

Apply a liberal dose of Softex or Soft Body one-part adhesive to the Super Hair / Flashabou tail along the entire shank and PAST THE BEND.  I find it easiest to use apply the glue with a bodkin.

Step 4

Tie in the light color bunch of Wing ‘N Flash underneath the shank just in front of the tail (about 1/3 of the way back from the hook eye) while the glue is still wet.  Take a moment to take the fly out of the vise to equally distribute the bunch of Wing ‘N Flash on either side of the hook bend.  It is far easier to do this now, before the glue has set, than later.  DO NOT TRIM the butt ends of the bunch.

Step 5

Tie in the darker color bunch of Long Brite on top of the shank at the same spot as the bottom bunch (about 1/3 of the way back from the hook eye) while the glue is still wet.  DO NOT TRIM the butt ends of the bunch.

Step 6

Advance the thread tight to the hook eye, taking care that the dark color stays on top and the light color stays on the bottom.  Comb through the bunches (both behind and forward of the hook eye) with a bodkin to remove any snarls that may have formed when pre-tapering the bunches.  Next, apply an additional liberal coat of Softex or Soft Body around the exposed thread wraps and along the back PAST THE BEND.  Apply a small amount of glue along the belly fibers.

Step 7

Fold back the remaining Wing ‘N Flash / Lite Brite bunches and tie down.  I typically reverse and tie down the dark color first to prevent any spillover of the dark color to the belly.  Whip finish.  Mushmouths made with Slinkyfibre or other fibers will require a trimming with a pair of long-bladed scissors for a natural, tapered shape.  Squeeze and stroke the fly until the desired shape is acquired.  Clear the eye area of any random flash filaments as they will make the epoxy application messy and difficult.

Step 8

Apply eyes, cover with 5-minute epoxy and let dry on a rotating wheel.  You’ll find it easier to apply the epoxy if you let the Softex dry before application.  I can typically apply epoxy to six size 2/0 Mushmouths when moving quickly.  Larger flies and eye sizes will only let you do two to four flies per epoxy mixing.  Smaller flies and eye sizes will let you do more per mixing.  I do not use 30-minute epoxy for this task as it is less viscous than 5-minute and tends to bleed into the belly fibers, thereby reducing the gap.
