The tried and true set up that worked so well for many years before any of us started using DR's was a flatfish and a dodger off a 3oz banana weight. You could feasibly use less weight since there is no tide to contend with in Lk Wa. You just need to get down to around 70' (+ or -) and be able to work the lure slowly maintaining a steep line angle. I actually prefered this to DR's because of the slower speeds and because you can get a better hook up on the fish without having to pop the 'rigger. Them sockeye are weird biters and tanglers too; it's easy to lose them at the get go since they bite light, have soft mouths and always seem to twist and pirouette instead of running like other self respecting salmon. As far as worrying about the fight, heck a flounder fights better. But if pure light-line sportfishing is what you want then you're better off chasing largemouth and Donaldsons. Reds are about the Barby. Lk Washington sockeye is urban meat fishing at it's finest, baby. \:D

IMHO, the only salmon that tastes better is a springer. ;\)
