Marshmallow Nymphs
When I was a boy, when I first read "Matching the Hatch" by Ernie
Schwiebert and "Trout Streams" by Paul Needham, I got excited. Secret
scientific knowledge about fish behavior and innovative fly tying was
about to put me into more fish than I could ever imagine. I was sure of
it. Paul Needham's revelation that trout take nearly all their food in
the form of riffle bottom nymphs was the key. My logic was
self evident. If trout took ten nymphs for every top water adult, all I
had to do was invent the right nymphs, specialize in fishing near the
bottom, and I would catch ten times as many fish!
Now that I look back on it, some 25 years later, I'm not so sure I
was that far wrong. The best fishermen I know are nymph fishing masters
who fish upstream with a weighted leader and a tight straight line, who
set the hook frequently, testing each bump, nudge and wiggle along the
bottom with a sharp, quick twitch of the rod tip. Until recently, I had
nearly given up on my early faith in the power of creative fly tying.
My long time fishing friend Patrick--who has out fished me consistently
and continuously for fifteen years--relies almost entirely on a small
repertoire of traditional nymphs, including the George's Brown Stone,
Montana Nymph, Bitch Creek, Hare's Ear, Latex Caddis, Zug Bug and just
a few others.
What I hadn't foreseen as a boy was how hard it is to detect the
barely perceptible taps of the curious trout that sucks in a drifting
nymph, and then spits it out again in the blink of a frog's eye. Nymph
fishermen do indeed get many more strikes than dry fly fishermen--but
most of us never even realize it! The latest fishing tackle, the
hottest flies and valuable streamside experience are available to all
of us who work at it and seek it out. But what sets the very best nymph
fishermen apart is what's hardest to come by: the lightning quick
reflexes and the predatory eyes, ears and instincts of the hunter. Some
fishermen have it, and some don't. Until recently I was resigned to
leaving it at that. But that was before I discovered Marshmallow
Nymphs--before I so suddenly pulled even with my friend Patrick, after
a decade and a half of lopsided competition, and started catching many
more fish than ever before.
The secret to the Marshmallow Nymph is not appearance so much as
texture. Marshmallow Nymphs are made from soft, spongy open cell foam.
They look and feel so much like the real thing that trout don't spit
them out right away. When fishing with soft bodied nymphs, I often find
myself pulling my line out of the water in casual preparation for
another cast only to find a determined and totally unexpected trout
still clinging to the soft, lively nymph at the end of my line. On
other occasions, I have many times watched my leader zigzag slowly off
through the current, even though I hadn't felt the slightest trace of a
strike. In thirty years of fly fishing, I have never seen that before!
As is so often the case with valuable inventions, I discovered the
Marshmallow Nymph largely by accident. I had an idea to create a series
of nymphs with closed cell foam. A slightly buoyant nymph--pulling
upwards against a weighted leader--would keep a tighter line, I
thought. It would be easier to feel the elusive strikes of the
riffle bottom feeder. But closed cell nymphs turned out to be too hard
to sink. As an after thought, I tried making a few nymphs with
open cell foam. And the results were spectacular.
Unweighted open cell nymphs quickly become saturated with water,
adopting a natural, freely drifting neutral buoyancy. But there are a
lot of good looking nymphs around. The real difference happens after
the strike. At the moment when most flies are quickly and
unceremoniously rejected--with a quick pooch of a finny
mouth--Marshmallow nymphs seem to trigger a short period of chewing and
tugging: just what the uncertain and heavy handed nympher needs.
The materials and tying techniques for Marshmallow Nymphs may be
new and different, but the fishing techniques don't change at all. I
try not to cast too far out when fishing with nymphs. If I see a good
holding lie fifty or sixty feet away, I'd rather make a series of 25'
to 35' casts in the intermediate water first, while gradually wading up
to the better water. I'll make a long cast if I have to, or even just
for the fun of it sometimes. But I don't often catch much beyond forty
or fifty feet, even when I'm fishing with Marshmallows. Long casts are
for dry flies and streamers, but not for nymphs. I try to strike a
balance between a tight, straight line and a natural dead drift, but I
do lean heavily toward the tight line end of the spectrum, and I set
the hook frequently.
As a fishing guide, I spend a lot of time showing beginning nymph
fishermen the ropes. And the first thing I work on is setting the hook
more often. Beginners often seem to think they've made a mistake if
they set the hook, and it turns out nothing was there. Nymph fishing
into the watery unknown is like a series of questions locked in the
infinite loop of a computer program: "Is it a strike? Is it a strike?
Is it a strike? ..." There's only one way to find out. You have to set
the hook. Sometimes you catch a fish by accident. That's happened to
all of us at one time or another. But if you're lucky enough to feel a
strike first, when you feel that unmistakable double or triple tug on
the end of your line, even the experts react more quickly. And that's
why Marshmallow Nymphs work so much better than any other nymph I've
ever fished with; with Marshmallows, you may not be getting anymore
strikes than you would, say on a Hare's Ear or a George's Brown Stone,
but you'll definitely feel more of them happen!
