You may want to tie some of these on larger hooks for King salmon. Humpy, Black Gnat, Adams, Wolf, and irresistible patterns are great for Grayling and Char. Bring several sizes of flesh flys with a dab of orange on it. They were working on everything last year. Include your own favorite trout and salmon flies.
Favorite flies seem to catch more fish all over the world.
A couple years ago one of our guys was catching silvers on a fly he used for marlin in Mexico. Our fish up here like action in the fly especially when dry fly fishing.
