Dual tube system

Paul,

I never tied these flies on heavy tubes, but I guess that using copper or aluminum would be an option. Personally I'd go for weight in the lower tube the main reason being that the size of these flies would mean adding a lot of weight using a full length copper tube. I also think the concentrated weight in the front of the fly would induce a nice, diving motion.

I don't think the fly would turn upside down no matter what you did with weight, because the wing on the top of the fly would keep it upright anyway. But you'd have to test this yourself.

And speaking of weighted flies: I personally prefer a heavy line to a heavy fly - especially in this weight class. I hate casting both, but a heavy line and a light fly seems to be more manegable than the opposite.

PS: Pete Gray who originated these flies, sent me a new set of pictures showing how to tie them, and I think a whole new article on the subject will find it's way to the site soon.

Michael,

I mount the junction tube before I tie, and simply join the tubes using the force of the thread. This pinches part of the junction tube between the two tubes, and gives a very durable fly, where you can still slip a hook inside the soft tube, which extends the lower tube. I have never needed epoxy. The thread and materials alone seem to hold the tubes together very well.
