After doing many self line tests I personally would not even consider using Fireline anymore. It is great line for the first dozen or so trips out and then it begins to fray turning from a black color to a gray. At this point the line has lost almost half of its strength. More than once I have lost steelhead while setting the hook with Fireline.
I like Power Pro although it does have a nasty habit of twisting around the rod tip. I have used Power Pro on all of my rods for more than a year now and have experienced no problems with rod/reel wear or breakage. I tie directly to the plug when trolling with no problems but would not do so if drift fishing.
Tuf-line is good stuff (not Tuf-line plus) and works fine but frayed on me when I was trying to slide the bobber stop up and down the line. Otherwise the stuff worked great, landed many spring chinook with it last year. Tuf-line tested very well in the line test done about 2 years ago by the way (saltwater magazine, forget the name). In general the line test demonstrated that braided lines have poor abrasion resistance and high tensile strength.
Bottom line: Try Power Pro, you won't be disappointed. If your going to be using it for drifting, add some mono leader on the front for abrasion resistance, otherwise tie straight on to the lure. Good luck!!
