To the original question, I have to agree with peregrines suggestion of at least an 8 wt. Here in MD, I've landed numerous Striped Bass, up to 30 inches on a 6 wt, hooked while fishing for smaller fish, and that light rod was fine. Striper's are strong fish, but don't make the blistering long runs that many of the species you'll find in Florida are known for. Up here, I generally use an 8, 9 or 10 wt for the majority of the fishing I do, when targeting the larger Chesapeake Bay tidal water species, and primarily because of wind & the size flies I throw.
An 8 wt will give you much more control over not only your line & flies when you encounter windy conditions, but more so over larger & possibly speedy species that you may find attached to your fly than any 6 wt could! The 6 wt will very much limit your options of fly size under such conditions!
To add to the list of recommended brands, you may be interested in checking out Colton fly rods. Although I have no first hand experience with them, they have a large following among Northeast coastal saltwater anglers, and I've read many great reviews on them,(from actual anglers) including several about how well they handled fish in Florida waters, including large Tarpon. I have yet to hear of anything negative about them, plus the prices are very reasonable! Colton will likely be my next serious rod purchase!
My current saltwater rod brands consist of TFO, Diamondback, and I've just purchased 2 Redington Crosswater 9 wt's, (one for my son, the other as a back-up, couldn't pass up the price
) which are all more than adequate for the bay species I usually encounter, even the occasional Spanish Mackeral!
