Dual Tube Phlyz

In an effort to entice larger striped muggers (stripers) during the spring herring run on Cape Cod when big fish venture back into the shallow estuaries to the herring runs, Pete Gray started tying 8-12+ inches herring flies on double tubes.

DualTubeHerringPhlyz... my very own... PharSidePhlyz developed and produced here at Area61! There aren't too many phly guyz in these parts who have opted for this methodology. Clousers, Deep sand eel variations, and Deceivers reign supreme as does sinking and intermediate lines and the soup dejour... they have a place in the big scheme of things!

I'm not a big fan

of the standard tubular classics... granted, they serve their purpose and catch picky river preditors... I was more motivated to combine flat wing/deceiver/hollow tie/whatever to my particular tastes and applications and isn't that what innovative tying is all about anyway!?

The junction tube

seated at the end of the body tube had the hook running too far back for my liking, so after some R&D at my DynaKing and numerous visits to the fly drowning pool (back porch hot tub) I developed some promising prototypes of my own design and notion.
Larger BigEyed epoxy heads proved effective as did the slightly lighter but esthetically pleasing Jungle Cockeyed versions.

With the incorporation

of my tandem junction tube I was able to move the centre of gravity forward for a more natural and enticing appearance and, since the muggers seemed to prefer assaulting head on, my hook up rate improved as well.

I don't like

using these when the toothy Blues appear out in deeper waters because of the shredding that goes on. Older tired soldiers get sacrificed now and then but the Blues attack from the sides trying to cut the fly in half. Trailer hooks might help but that's not my thing. I like horizontal Stripes best!

I prefer heavier 10-11 weight gear

overlined with floating lines. Casts are not long and the drifts are key with the undulating motion of the long hackles that brings out the beast and 6 feet of 20 lbs. flourocarbon simplifies the basic presentation! Tapers are optional and effective for longer casts.

My goal is

to "insinuate" movement and mass without trying to throw heavy phur n' pheater look-a-likes. For my efforts, the DualTube is spot on with the hook up front.

Good evening Pete, ...

Good evening Pete,
I don't know how to express myself enough,
Your Double Tube idea is perfect........ I think describes it best.
Of all the items on this site, to me this is it !
Your double tube has changed my ideas and thinking for both the salt and the freshwater for ever.

So simple, its been there all the time, but I never saw it.
And as a bonus the fly will ride vertical always.

Many thanks again for changing my fly World.
Kind regards,

The example shown by...

The example shown by Martin captures my tandem application intent nicely...
A minor suggestion would be to shorten the lower tube in order to bring the hook junction (and centre of gravity) as far forward as possible.
Most of my lower junction tubes are only 3/8"-1/2" long with just enough trailing soft tube to properly secure the hook.
Besides the thread wraps, I'll use some zap-a-gap or epoxy to weld things together and then apply the phinal phur n' pheathers and eyez to complete the desired "interpretation".
Less is more...Sparse is good...The intent is NOT to create hampsters or stuffed animals but to present an "insinuation" of shape and movement...
The long flowing material will undulate with the slightest currents during a dead drift (stay just tight enough to detect an assault) occassional irratic strip can also provoke a mugging...
Time onthewater is the best teacher and a good prozac alternative!

re: that "air chair"...I've got a knock-off...When I say I'm just hangin' around, I really am! TWO (2) thumbs up!

re: CRAP!!!!..."Where was I"...sorry, "just hangin' around!" Too bad I missed the cut...I posted my DualTube on flyfishingforum a few years ago and posted here sometime last August...maybe I'll make "Tubez part Deux, the Next Generation"
Go figure!?

CRAP !!!!! where were you when I was putting my book "Tube Flies Two:Evalution" together, I just gotta send this to my Neurosurgeon who fishes Stripers in your neck of the World. WELL DONE

This may be a dumb question but how do you rig the dual tube? You'd have to run the line through the lower tube to take advantage of the more forward hook so I'm guessing that's how you do it. I'm also guessing the wing causes it to swim right-side up. Let me know if my assumptions are correct if you don't mind. I love the idea. The more forward hook placement would really increase hook-ups.

You figured it out yourself: the line goes through the lower tube and the hook will hang short of the longer top tube and tail.

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
