The 2-Salt Tube is a modern intruder-style tube fly designed primarily for steelhead and salmon, but with enough versatility to cross over into light saltwater applications. It is built on a tube rather than a traditional hook or shank, which allows for a free-swinging trailing hook and gives the fly a longer, more fluid profile in the water while also helping prevent leverage during the fight. The pattern typically blends materials like marabou, rabbit strips, flash, and sometimes rubber or silicone legs, creating a balanced mix of movement, profile, and subtle flash rather than relying on one dominant feature.
