I am a dedicated nymph fisherman, but, do not use "rigs". I, also, do not use an indicator. I watch my fly line like a hawk! I weight my nymphs when I tie them and will fish one nymph being either #10 or #12 or swing a #12 or #14 unweighted wet fly on 6 feet of tippet attached to a 7' furled leader. I make my own furled leaders from Berkley Vanish flurorocarbon in 4 pount test which sinks faster than any material I have tried. I purchase bulk spools of clear Ande regular mono in 4 pound test and 6 pound test and that is what I use for my tippet material. I use the 6 pound test for my nymphs and the 4 pound test for swinging wets. Last Sunday I fished our local trout stream and found the water very clear and I increased my tippet length to 10' and caught 37 trout. This is my style of fly fishing whether it is the "norm" or not. It works for me and I love fly fishing.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
