Just joined the site after reading your post. I'm the guy that was catching all the flounder. You had your FSU jacket on and you helped me land the last one with my drop-net. I was wearing a black, Fear Factor ball cap.
I've been fishing for flounder at Jetty Park, about once every two months or so for the past two years. Most of my luck has come late summer. I've caught a few that went about 24". Never really tried this time of year before but I was in town so I had to try.
Normally I've been using a basic bottom rig (egg sinker, swivel, 20 lb fluro leader, #2 kahle hook). To this I hook a live shrimp. If I can find finger mullet with ease, somewhere along the 528, I'll use those but mostly I'm uing live shrimp. I wouldn't try to use anything but live bait although maybe artificials would work (haven't tried it much).
On Saturday I set up one line like that but I got sidetracked with my other line where I tied a white lead jighead to my leader (20lb fluro). I hooked a live shrimp to that and that's what all my flounder came on.
One thing I do, regardless of my rig, is to keep your bait on the bottom and slowly move around. Watch any of those guys who flounder fish regularly and they're always moving around. Slowly but steady. The area I was in is a good one but anywhere from where you were on the corner to halfway up the pier is good (biggest one I caught was on that corner facing west). Heck, the far end of the pier might be good, but I never go that far because I do well on the close side.
Let me know if you have any questions.
