My only experience with them was on deep hardware or bait, but I caught a bunch when I lived in Florida.
But if you find them rolling up in the mangroves they will hit flies, I believe. I would definitely think about sink tips. I learned they roll high but hit low. That was years ago from hardware flinging heathens. Your mileage may vary.

Stonefish provided some good links.

Why don't you call a guide and see if he has a mercy trip, or needs to fill a boat or can help a jonesin' fisherman from Poundtown, wherever that is. State your case; the worst answer is "no."
