Yeah, green sardine seems only to be really important for the halibut. Pete and Brian both got more fish than I did with rainbow trout color big hammers. Another variation of the green sardine that I really like is kind of a brownish color. It's the basic pattern of green sardine (green back w/ black spots, pale yellow stripe, clear/sparkle belly) except it has more brown in it (brownish/green back, same yellow stripe, brownish/sparkle belly) It's really good for bass and I've also done fairly well on the halibut with that color. Howard just brought anything green that he had and slayed the wsb the other day. So, color doesn't really matter very much for the wsb as long as it represents some kind of bait fish. A brown bait or clear/red flake probably wouldn't produce very well. Pick yerself up some green sardines in 4 and 5 inch (4" for halibut, 5" for wsb). Fish the 4" on 1/2 oz. heads and the 5s on 1 oz. heads. And get some rainbow trout and then get a couple that YOU think look good. If it looks like an anchovy to you, it'll look like an anchovy to a fish.
