A saltwater reel with a good drag is an excellent idea if you intend on searching out the big fellows. Backing should be 30-pound to handle the abrasions of shells, grasses and occasional storm debris. One hundred yards will do but 150 is better. Flies should be tied point-up in bead-chain Clouser and Crazy Charlie styles to minimize grass fouling. Hook sizes #4 and #6 are appropriate, and sharpness is essential. Chartreuse-and-white, red-and-white and yellow-and-red are favorite colors, but frankly these fish proved a very cooperative predator.
The only drawback to the long-rod visitor at this specific area is the limited number of genuine fly-fishing guides. That's both a blessing and a curse. While you do have to make guiding arrangements in advance, you won't have much competition for a flat. There are two angling stores in the area, and they can help make the necessary connections. Also Fred Lynch is a full-time guide, and specializes in fly fishing, so you can't go wrong if you get on his schedule.
