I have been using the Rio Gold fly lines for years, great fly line. I mainly use mine on dry fly rigs, but it would handle any fly you cast.

For nymphing, if you are going to be using a large nymphing rig (strike indicator, split shot, large heavy top fly and a bead head dropper) I would suggest the Rio Indicator line, that is what I use on the larger rivers in WA and Montana.

Rio makes great lines, you can't go wrong.
