I have the full set for my TJ. I have the front and back roof on, bur haven't used the sides yet. I'm in central FL too, and the spiderweb is great in our climate. It provides enough shade to keep the temp down, without feeling like you are closed in.
Visibility is fine, it's like looking through a screen door. I don't really notice it there. If you have ever been in one of the old hondas (crx?) that had the colored glass in the hatch, or an old school rear window for a pickup, that has the painted screen, that's what it's like. You can see fine night or day.
Get the better mesh- it's a night and day difference. The better mesh is much finer weave and very smooth to the touch. The other mesh is rougher and more open.
Stop by the store, and take a look at them. That's what I did, and it made the decision much easier touching and feeling the fabric. Chris is a nice guy and will probably have his jeep there so you can see it in place. I noticed the Jk at the electricians office up the block also had one on while I was there.
