I ALWAYS run 12# P-Line high visibility main line for steelhead fishing. It is very easy to see if you depend on seeing your line while drift fishing, like I do.. You can tell a lot about what is going on under water by what your line is doing. I use a 10# Maxima Ultra Green leader material, length varies by water color and flow. I never pin a corkie like a lot of people do and catch a lot of fish. I run a bait casting reel and run the drag fairly loose so I can have total control over the pressure I am putting on a fish. I have NEVER had a fish break my main line, and have pulled my boat off anchor several times trying to break it off when I am hung up. It is all about putting in time and finding what works for you and what you like. I personally dont think there is a need to ever use 20# line for steelhead fishing. For salmon fishing I use 50# Power Pro and a 40# Maxima Ultra Green leader. What ever you are doing with braided line, I highly recommend using a good mono shock absorber. Meaning never run braided line strait to your hook, any sudden shock will break it. Hope you get lots of good help from the comments here, every one has good lessons to teach if you just ask for help.. Good luck out there.. Tight lines.
