Guideline's brand new Coastal Evolve WF fly line has an optimized taper with slightly more mass in the front part to effortless turn over the fly in harsh coastal conditions. Guideline has designed the line for sea-run brown trout, sea bass, mullet and other coastal species that live in shallow water and require long, careful and precise presentations regardless of the weather conditions. Coastal Evolve has an improved and somewhat thinner shooting line to give less friction in the guides and thereby longer casts in difficult conditions. The colour of Coastal Slow Intermediate's head is Ice Green, while the head of Fast Intermediate is a slightly darker Sea Green. The shooting line is a clearly visible Sunrise Yellow that makes it easy to recognize where the taper of the head ends and the shooting line starts.
