A few months ago I asked a question regarding leaders. A couple of you responded that you use fluorocarbon tippet material for all trout fishing, including dries. I haven't tried it, and the snow outside my window tells me it's going to be a while before I can try it. Now, I've always heard that fluorocarbon was great for subsurface pattens because, among other qualities, it's density was greater than water, thus sinking more easily than nylon. This sounds like a contraindication for use with dry flies. Perhaps the difference is in "sinking" is negligible for dries. Any thoughts? Thanks.
