With all the talk of which rods you've forgotten the most important "gear" for that particular stream: CANS AND CANS AND CANS of bug juice. Had two of the buggers land,one on each shoulder, and peer around my head and one asked the other if we should eat him here, or take him home for dinner later.
Although it's been years since I've been there (doing the 'mid-night sun trip fly in at 6, guy picks you up at 6) the pilot said best fishing would be from 10pm til 2am. Little to show for it until 10:01 and it was one fish after the other. 201am ... it was like someone threw a switch. zip, nadda, nothing. Never seen anything like it before or since.
Other than that gear suggestions are top of the line.
