Hi, I'm a fairly new to fly fishing and I just recently bought a Sage FLi 5 wt. I'm trying to figure out what fly line I should buy. I'm happy to spend a little extra for a better line. I'll mostly be trout fishing on the Bow or some smaller streams around Southern Alberta. I'm looking at getting a weight forward, but should I consider a double taper? I've been recommended the SA GPX, Orvis Wonderline, Rio Gold or CortlandR 444. So many to choose from! Any recommendations? Thanks!
