I have been successfuly trolling the coyote spoon for quite a few years, for both returning spawners, and Blackmouth. I agree with most of what has been said. some people dont understand that there are two kinds of Blackmouth, there are the ones that move in and out with the bait, and the ones that stay in an area for long periods of timeregardless of bait present. the free ranging "bait herders" are usually the fat football fish, always having bait to feed on, and then you get the skinny fish, which feed oportunisticly (sp?) on whatever happens to be around.
I have caught Blackmouth as deep as 190 feet on the spoons, and as shallow as 50 feet.
I think its where you find them, and where you spend the most time fishing.
personaly I fish the ledges and drop off structure, adjacent to deeper water, staying on or near the 90-120 foot mark. with bait either suspended, or on the bottom. the green glow hot-spot, with 36 inches of leader(48" for adult Kings) back to the spoon Jeffhead mentioned (green chart.-glow) is what I always start with. smelly jelly herring on everything from the spoon to the flasher, and ten feet up the line. twelve feet from the release, the release three feet up the cable from the ball, and then drag the ball in the mud.
