Swinging for nookies is always fun, especially when they are fresh. I have caught kings before by swinging marabou speys and bunny speys as well. Also, Egg Sucking Leeches are always a good pattern to have as well. Smelt and Alewife patterns are my favorite for out in the lake(when conducting what I live for...surfs up steelhead/salmon) but I downsize in the rivers.
This year I plan on doing a little more swinging if time allows.
Peter S-C, are you fishing these on sink tips or intermediate lines or what?
