I have been tying tandem streamers for awhile now and use 30lb. mono. line for my tandem hook ups.
BUT, most of the old tandem flies were tied with wire. So... anyone have any idea what kind of wire was used? Where can I get some???
Mono works fine, maybe better. But mono does have a long shelf life either.
I guess I would like to tie these like the ones in by gone years.

Thank You!
