Trilene XL is good line. It is my preference for light mono needs. 8# test is heavier than I use for walleye fishing, I use 4# and 6# and get more strikes with the smaller line diameter.
I have gone through a transition in the last couple years. I still have rigs set up with mono, but I also use Power Pro for much of my walleye fishing, especially in the river. If you back the super line with a little mono so your spool fills properly, the PP cast a jig just as well. The sensitivity given by a no-stretch(super line) will by far surpass any mono. Anything that line bumps is transmitted directly to the rod without the cushion effect(stretch) of mono.. A super line will allow you to detect extremely subtle bites that mono will not transmit to the rod.
Other advantages of super lines is extremely small line diameter. The smaller line diameter, the less current drag on the line which will allow you to fish the same jig more effectively, or sometimes allow a lighter jig to be fished effectively.
Trolling with super lines has advantages also.. you can see the lure action on the rod far better, and you can detect debris hung up on the lure much easier. Super line should be used with a softer rod in trolling applications.
I have never had a problem with superlines in the river(stained water) due to line visibility. Regular mono lines still have their place, but I am using power pro most of the time now. I have tried different super lines and like power pro the best by far. Its much more limber once its broke in(breaks in quickly).
I was the biggest super line skeptic there was a few years back. I can make mono work for everything.. but the super lin just works better for many things. I guess an old dog can learn new tricks.
