I have an 11' 3/4 that I had Steve Godshall build a nymphing line for. It's a taper he calls his nympher supreme and is basically a beefed up scandi that turns over heavy flies and an indicator with ease. It's and integrated line so it shoots through the guides with no issues and has a head of 27.5 feet and 226 grains, a handling section behind the head, and slick coated shooting line behind that. Awesome line for nymphing, and pretty nice for swinging as well.
