I'm usually using four foot leaders with sink tips for winter steelhead. My dirty water leader is a single strand of .0148" P-Line CXX (nominally 12 pound test, but probably much stronger), with a triple surgeon's loop at the top end. (I wouldn't trust a perfection loop there, in a tug-of-war with a good tippet-to-fly knot.)
For "steelhead green" I use fluorocarbon leaders such as this: 10" of .017" Orvis mirage, 16" of .015" Mirage, and 22" of .011" Mirage. Perfection loop at the upper end; sections joined with uni-knots. But wait - there's more. Below the loop is a short, sealed wrap of butterscotch thread. Why? To identify the tippet diameter; other colors for other strengths. And there's a short wrap of black thread between the top and middle sections, to identify it as fluorocarbon.
I enjoy designing and tying leaders and leader systems, obviously.
