I have actually caught about 2 rainbows in my life the size of some of these steelies, well, not quite, but mine are good for rainbows. See "TroutFishingBear's 2004 Trout Of Fame" in pictures to see the rainbow trout version of this post.
Great steelhead, it would be cool to fish for them! But imagine catching them on 4 and 6 lb. test like I catch my rainbows.
