Hi all, after having seen some posts on Jack Field's instagram about using tungsten "thread" (really a thing tungsten wire) instead of normal tying thread, I'm curious if any forum members use it regularly or at all. I can definately see how tying with tungsten wire can pack on weight without bulking up the profile of the fly, but is the effect significant compared to weighting flies with lead and using a thin conventional thread? Is the difference worth the cost of tungsten wire? It sounds like a cool concept bur im concerned with the ability to make neat/invisible whip finishes in front of dubbing collars etc.
