Various techniques will work for those stupid Lake Wa sockeye.
The favorite method these days seems to be the two red/pink/orange bare hooks behind a flasher method. Leader length usually dictates trolling speed. You can troll faster with a longer leader. Doesn't matter too much, as these fish are stupid. Since they are soft-mouthed fish, expect to lose a few with this method.
You are best off by running your gear on a downrigger, as it keeps everything all nice and tight under your boat. Or, you can be like the "zoo" out there and run banana leads, divers, or whatever else you can find. If you go this method, bring plenty of rods and gear, as once you hook up on a downrigger cable, you can kiss that line/gear goodbye. Well, that is what seems to happen when people hook our rigger lines. Dunno why, but steel cable always seems to win out over monofilament or braided lines!
To increase your odds of hooking up, run as many rigs as possible/legal. The more dodgers you have down there, the more those fish like to come and investigate. Usually, when one rod his hit, they are all! It's fun fishing until that ONE guy needs just one more fish. 7 fish in 10 minutes, followed by trolling around for hours for that one last stupid fish.
A standard steelhead rod/reel will work just fine as your rigger rod (until they explode on the hookset).
If it were legal to do so, and I DO NOT know if it is, I'd put out some dodgers on the riggers (no rods, no hooks, etc), just to make some noise down there. Maybe run 3 fake dodgers, followed by the one with the hooks. I bet that would work really well, if it's legal to do so.
You can also run a Coyote spoon directly off a rigger. Try doing that with a really light spinning rod and light line. Way fun! Way more fun than having to fight a dodger.
These sockeye don't put up a good fight, so it's a meat fishery. Most of the fish that I have seen attempted to be C&R'd end up dead on the surface. Kinda fun to get one on a light spinning rod and light line. Almost makes it a challenge.
Back "in the day", a lot of folks used to try Flatfish with various degress of success. Personally, I don't think I'd go that route.
