i love finding the fish you are talking about, most of the time these fish are pretty much left alone, most folks arent even aware that they are there. when i find the fish i vertical jig a kastmaster or a smoke tube. but there is a little more to it than just finding them and jigging. i may look at the fish using the graph several times over the course of the day and until i see what im looking for i pretty much leave them alone. im looking for bait to be close to the school, if theres bait close by they can be caught vertical jigging, if no bait is present then it gets a lot tougher to get them started.
the downside to jigging over a compact school is spooking the school by releasing fish, obviously you have to release short fish, but even if you dont intend to keep the fish you should put the legal fish in a pre-prepared livewell until you are done fishing the school, and then return them to the water before you move on.
i sent mhall a pic of a stump bed on an offshore hump the other day, we discussed that it should be any day now. im glad to hear you are seeing those fish in that pattern, wont be long now and we will be seeing the same thing on LC
