Rio standard bonefishing line. A great line for casters that like to carry more line in the air. This line shoots very well. However, the longer head will allow you to pick up more line without needing to strip in as much line. For newer anglers, wading anglers, or very windy conditions try Rio's Bonefish Quickshooter Fly Line. The Quickshooter line functions more like a shooting head line- shorter, heavier head, designed for shooting line.
