I would get a season pass at the pier with the most Hotties which usually means the pier with the biggest parking lot and least aggressive parking lot enforcement.
Back in the day I always fished Nags Head Pier on the Northern OBX because of the Hot waitresses that worked in the pier house restaurant.
I would also put out a bottom bait on a heaver, have to go through a lot of Rays and Sharks to get the Cobia, but the Cobia do a lot of feeding on the bottom and when you have one on a Drum rod with a 9/0 hook you can really put the heat on him, unlike if you are worried a little #6 Treble is going to fall out or straighten.
You get grief from some of the pin riggers but if the water is not really clear, I would rather have a bait on the bottom.
You just have to take care to be able to break off any Shark or Ray before he gets into a King Rig and put the heat on whatever hits your bait to try and get him to the surface to have a look at what type of Flattosaurus you have on.
Biggest Cobia I ever had on in my life was on a bottom bait of center cut jumping mullet with Abu 9000 and a Surf Stick, fish got off but that is okay, I still remember getting him on top and watching him swim offshore about 200 yards from the end of the pier. That was 25 years ago on Rodanthe Pier early May.
