We have a large selection of flies. Sockeye flies tend to be smaller than other salmon patterns and can be very flashy to dull. Greens, Chartreuses, Reds and Oranges are often the go to colors, but pink, purple and naturals can be good too. Check out Sockeye Lightnings, Sockeye Lanterns, Montana Brassies and Copper Swans. The Sockeye Orange and Sockeye Green are really good if you're looking for a larger hook.
When fishing, look for fish that are pooled up and holding. These fish are a lot more apt to take a fly than fishing that are on the move. Some rivers and streams allow two flies. Think about fishing a tandem fly set up with the two flies of different colors set about 18" apart.
Best of luck!
