I have been using Cortland Camo intermediate sinking line for years. It casts well and sinks evenly at a desired rate. In the past couple seasons, I've noticed that it was starting to get a little boyant and not sinking as well. This could simply be the nature of an old line that is scratched up making it float. So now I'm in the market for new line. Does anyone have any experience or opinions on other brands of line? Scientific Angler, Sage, Air Flow? So far, my research has brought me back to Cortland. What do you guys think?
