There is an article in the March 2009 Flyfisherman magazine about arctic char/dolly varden.
They had some help from Walt Maslen of www.northwestalaska.com He rents rafts and other high quality gear in Kotzebue and is a nice guy. He is also an active forum member by the same name "Northwestalaska". I have talked with him many times when planning float trips up that way. He is very knowledgable and a great resource for anyone taking trips up that way.
Anyway, below is a link to the article. If you get a copy at a bookstore, you will see my wife's picture in Walt's advertisement on page 47. She was proud of that 9 lb dolly. Anyway, a link to the article is below. Thought you may enjoy it. The Alaska part starts on page 3 of 6 in the below link.
Below are a few nice dollies we have got up there. 9, 11, and 14 lbs respectively.
