You could also consider Copolymer as your tippet, it is all I use, and it has a thin diameter compared to regular mono. I use 8lb P-Line Flouroclear Nail-Knotted to 4lb Flouroclear for Trout, and a straight 8lb Flouroclear for Summer Steel, not saying that I have had the pleasure of hooking a Steel on the fly rod.
Another good Copolymer line is Gamma.
