I am looking for a fly line to use with nymph fishing for trout in the mountains of Western North Carolina. I have used a GPX from Scientific Anglers in days past. I would like to explore one of the Teeny fly lines or the Rio Nymph line. I will be fishing with a five weight. I am very interested in the Teeny fly lines. I do not know which Teeny slow sinking line to use. Have any of you used one of these lines with nymphs in freshwater trout fishing streams. I would appreciate any thoughts and help with which one of the Teeny lines would be good for this setting. Or should I stay away from the Teeny lines and use the Rio nymph line?
