I like K15's on the coastal rivers, and K12's and K13's for the Columbia. I have done well with orange U20 flatfish, which is about the same size as a K12 for steelhead. Back when I lived in Portland, we knocked summer steelhead and fall salmon dead with flatfish in sizes of F7 through U20. Orange was the only color we ever did much good with, though I can't say we gave other colors too much of a chance. This was before the notion of baitwraps became popular (yup, I'm that old), so we just used them bare. Caught plenty of fish that way, too. I plan on trying one in a few weeks when I head down to the Columbia.
