For the past few seasons this has been THE king salmon fly to swing. The Chartreuse version is super hot in the lower river right down to tidewater. Guide Intruders create a large profile in the water and have the heavy eyes to get down where the big-boys hold.
If Pink ain't working move to Chartreuse. An awesome king fly that is super effective in tidewater or the lower river. We even fish it in the saltwater for kings in S.E. Alaska. Ostrich feathers give a full profile without adding much weight. Rockstars are approximately 4 1/2 inches long and are only weighted by a small conehead. A terrific fly to fish and cast all day long.
