Last year I fished with a local guide out of Cathlamet. He uses mostly silver/chartreuse & silver/red like everyone else. He changed up the size of the plug (K13-k15) depending on the speed of the current/time of the outgoing tide. He tried to stay away from the k13's because of problem with getting proper action when wrapped with sardine filet. Incoming tide it was off the anchor & went to trolling, but w/herring. He felt the color of the kwickie was not near as important as the scent + sardine wrap on it and that the kwickie was running straight & true. He changed the sardine wraps every 15-20 minutes so they were always fresh. I'm no expert on springers, saltwater fishing is mostly my game, but he got us into 16 take downs that day.
