I'm reading George Daniels' wonderful book Dynamic Nymphing. In the book he talks about using Stren Gold Hi-Vis line for sighters on his leaders. I fish a lot of streams that are heavily shaded. I've tried using Amnesia as butt material, but I find that if the material is 15 or so feet away from me I can't see it. So I'm wondering: Is Stren Gold more visible than Amnesia? Also, does anyone have experience using sighters in longer-line nymphing? Thanks, Randy
