I agree the jig head should be blue, black, pink, or purple. The body should be any combination of black, purple, and pink. My preference is a 1/2 oz. black jig head on a Gammy hook, with pink/purple body (cross-cut rabbit fur). But like Todd said, alot of different combinations are equally as effective. Go with what you're confident will catch fish.

In my view, twitching a jig is both easier and more effective than snagging. If those lunkheads I see trying to snag salmon illegally would just switch to twitching a jig, they would never go back to snagging.
