does anyone have any experience with the Cortland indicator nymph lines? I have a Echo Shadow 2, 10' 3wt that I want to use an indicator line on. The lightest line I could find is the Cortland WF4. Airflo also makes one but a video I watched about it said a WF4 is really a 4 3/4. Maybe too heavy for 3 wt? Thanks,
