icic! That's indeed an interesting situation. Kind of remind me of back then when I used to fish for tunas. The school of tuna is boiling on the water chasing balls of bait fish that is 7-9 inch long. I had great success using a floating or suspend jerk bait giving a fast twitching and stop action, usually I just cast over the balls and if everything went well, usually a bite is guaranteed. Sometimes when the fish went spooky, I cast a suspend one next to the balls ( like really close to it though, but outside of the ball ) Do some fast twitch action followed by dead suspending action, they will hit it like crazy too. I think the key is to maintain the depth and combines fast twitch with dead-stop motion to allow for reaction bites. A flashy jerk would really help too, since when the reaction happens so fast, they hunt for the flash...
But what do I know, Tuna is a complete different specie to bass, i.e. a faster and more active hunter than bass... but hope that my little experience could give u some idea or inspiration on tackling the situation and getting some success! I guess finding a way to catch those fish you found is part of the fun part of the game! good luck on that, and hope to see you posting some good pictures sometime later!
Not to promote any particular bait, but this video has a pretty good demonstration of the kind of presentation I am trying to describe. check it out if you are free.
