Whatever flies you bring, just make sure they have some chartreuse or pink on them. Clousers with stingers would be a good start as salmon will tend to short strke. I usually just cut the front hook off. Keep them about 3" long or so and add some flash. Surf Candies will work as well.
If you have a heavier rod then a 5, bring it.
7 or 8 would be preferrable for salmon, but a 6 wt with a fighting but will work in a pinch as well.
Have a good trip.
