“The first thing is you need to carry a substantial loop, not just several useless inches as I see a lot of people fishing with. You want the loop to be at least the length of a fair-sized steelhead, say, 30 to 36 inches. Cut this in half and you get a loop hanging 15 to 18 inches below your reel. That length is usually sufficient, but I sometimes use more.” (excerpt from Dec Hogan’s book @ Midcurrent)
