Not having tied any of this type of fly I thought I'd ask a question. Maybe some of you have tied these and have an answer.
The body of the 'Tube Fly' is obviously a tube. Now I've seen these (illustrated and photographed) made from with what looks like metal or plastic. What material is used for the tube and if plastic, any particular thickness? Can you use the small coffee stirrers or even some of the plastic 'Q-Tips'?
