I have used j-plugs for Springers in the Willamette and absolutely knocked the stuffing out of the fish with them. Trolled them at a depth of about 14 feet. I think kwikfish might be better, though.

I like j-plugs and silver hordes in the salt. I don't use them in fresh water anymore, just because I have other things I prefer more. But they would work, I'm sure.
