If you are going to fish Springers, you definately need to learn how to backbounce prawns, sandshrimp, or eggs as these are probably the top choices of most serious springer fisherman. Although trolled herring can be extremely effective at times, generally the baits above are going to outfish herring most of the time. I do like herring if the water is up and off color some. If you are getting a bite, feed these fish until they start taking line off your reel as they generally will swallow the bait if you let them(make sure you can legally keep them,or I probably wouldn't fish bait at all). Good luck.
