Description
This powerful line leads with a gently increasing forward taper capable of cutting through the wind or shooting line long distances—a true advantage when you’re chasing the likes of salmon, and other hard-fighting, saltwater species.
With a 30ft weight of 204 grains (13.2 grams), this line adheres to AFFTA specifications, meaning you’ll feel your fly rod casting the way the manufacturer intended, regardless of what brand fly rod you use. We tacked on durable welded loops at either end to make attaching your backing and leader that much easier.
