Love the GPX Series Richard Mon Nov 09 2015 I do mainly nymph fishing so I prefer this line over a trout series which doesn't seem to have nearly as much turnover power when roll casting. In terms of noise it seems to be less noiser in comparison to the old sharkskin line. I can't say it shoots better than the old one since I don't have the same weight line on the same weight rod but I feel it casts better than the traditional fly lines.
