A good rig for flounder has a big enough weight on the end of the line to "hold" bottom. Then, it will have two circle hooks set at 6" and 9" above the sinker. Tip these with either calamari or shrimp and you will just kill the flounder. I do this every time I go to the Outer Banks in North Carolina and I'm sure it will work there as well. Also, as Nate said...you don't need to use too heavy of a line. Sure, you have the chance to snap a BIGGIN off but you will catch more in the long run with a lighter line. Good luck!
