I really like the Bill Herzog drift fishing video. I think Frank Amato is in it too. Filmed on the Oly Pen and pays alot of attention to reading the water and technique.
They are a bit overenthusiastic playing the fish but the scenery is great and the info is awesome.
I also bought a 'Fishermans Heaven' compilation tape at the Puyalllup a couple of yrs ago.
Not so much info but entertaining if the rivers are closed/blown where you are.
Herzog available at Sportco.
