Here in Ak we catch a lot of them.
I like to use RAW shrimp for bait on anything custom jigs and spins makes. Sometimes we use Pautzkes balls-o-fire single eggs or skein eggs from Salmon we catch in the summertime on the rivers. the skein eggs seem to catch more rainbows and RAW shrimp catches mor Kokanees for me.
Rat finkees. shrimpos, ratsos, slender, spoons are some of my favorites. Pink and Orange seem to work the best for me. My fiancee likes a pink headed ratso with a white tail on it.
I will also use swedish pimples at times. Berkleys atomic teasers tube jigs in a white color seem to be one of my favorites lately.
