Be careful! Suit your line to the method of fishing you use. What works for juro doesn't necessarily work for me. Neither of our techniques or preferences may be YOURS!
For the GL tribs, I use nymphs, usually weighted, and normally with an indicator. That is tough fishing for the lines, but normally is the most effective means for taking steelhead.
On those quite rare occasions here when I can use his techniques, I change spools and use my better line. (That's the advantage of a spare spool!)
What I am saying, then, is choose your main fishing line to match the way YOU primarily fish. If you have the extra bucks, a spare spool with a different line can save a day for you.
