Bluefish, definitely makes sense. I just looked up how to tie a double bottom rig and what a ton easier and less expensive then buying those pre-made ones. The idea on the clear tubing is great!!!! Hopefully be able to post some pics of some good ones coming up soon!!!
Would the mullet be in the creeks by this time for some fresh bait?
Mullet may be around. I usually see them in the creeks/marshes during milder winters.
Quick disclaimer: I no longer live in SC and only fish in SC when I am home- 3-4 times a year. Traditional patterns to me may not be the case anymore.
Sandfleas should be available in the surf. Look for v's in flood zone of the surf.
Pier fishing may be more convenient. To make bottom rigs work better, try to find gold hooks and put a red bead in front of the hook. Eagle Claw makes gold baitholder hooks. Aberdeen- stype crappie hooks will work, but do not expect them to hold up to anything over 4 pounds.
If you want to fish lures, casting a 2 oz sting silver on a light surf rod wouldn't be a bad idea if bluefish or Spanish mackerel are around(you will probably see glass minnows breaking if they are actively schooling).
