If you had a light/generator setup, it makes things A LOT easier.... But live shrimp under a popping cork is pretty unbeatable for a line tug. You have a lot of species running through the Dike area. If it were me, I'd go all the way down to the end and fish the right hand side behind the guard rails, you'll know what I am talking about when you get down there. Live shrimp under a popping cork, with about a 3 foot leader should do the trick. Like I said, if you had a light setup, it will increase your chances at night.
For the big uglies, or reds, you can get a "Redfish Leader" setup from Academy, I think H&H Tackle makes them pre-made in different weights. I usually use a 3.oz pre made redfish leader setup, comes with the hook and all..... They are packed individually in a small clear ziplock with yellow label. I'd just buy a few dead mullet and cut those up in 3 pieces, hook one on there and let it rip. Set your clicker and wait.... Make sure you are fishing during the tide movement, either in our out..... Hope that helps, good luck, and tight lines.....
