What to tie?

I've booked a trip to Alaska for the last week of July/ first of
August, we are going to be staying at Big Dave's Alaskan Bush Lodge, near
the confluence of Lake Creek and the Yentna River (about 55 miles northwest
of Anchorage). The place is supposed to be good for Rainbow, Pike, and all
five species of Pacific Salmon. The outfitter says he will supply all of the
flies we need so don't worry about 'em, but I kinda prefer to fish with what
I tied myself. Anybody have a suggestion of what patterns and sizes I should
start tying?
