Last season was my 3rd season running copper. I now own a 200, 300, 450 and 600. Most days from May thru September I run one down the chute. Some days I run two on the big boards. All I know is that my hookup rate over 3 years has increased 33%. Some days as much as 50%. During salmon season, nothing beats a white or chrome e-chip down the chute with a green crinkle fly. I usally don't post much, but I would have to say that adding at least a 600 would be a smart investment.
