You are getting some good info here! I too fish the herring on a 6 foot leader with an 18" dropper and 3-5 oz., and you have to drag the bottom - those springers bury their nose in the sand. I use fresh herring I jig from the Harbor, big run that time of year, and I use plug cut hog herring, bigger the better and the tighter spinning the better. And dead slow, always into the tide but backing down through the drift. Another thing I noticed is during the big runouts I just killed them out on the shallow flats - and I mean in as little as 3 feet of water - no kidding. Not only was I catching them up there but I was seeing lots of them on my sidescan sonar. What they were doing up there is anybodys guess but springers are crazy, or maybe lazy, staying out of the current?. When the tide slacked they moved back into the deeper holes.

I live down there in the spring - look for a 15 foot Smokercraft Alaskan with a big blue fish box, out where the sand meets the prop.
