Scientific Anglers UST Short Double Density Intermediate/Sink 4 Line

The double-density UST Intermediate/Sink 4 sinking Scandi head cuts straight through the surface, but the Intermediate section helps keep the fly speed up while the Sink 4 section brings the fly down to where the fish are holding. With the Intermediate section below the surface, there will be less influences by the current, providing excellent contact with the fly. This was a favorite line of the field testers in pools of medium depth and current.
