I can tell you that if I ever put in another pool, I would go with a SWCG, based on all the reading I've done here, as well as talked to others in my area that have them. I use a trichlor feeder and bleach right now, and it works well for me because I run a high CYA pool and my pH tends to want to drift up, but it doesn't work well for everyone.

From everything I've read, it sounds like a way to make the pool as maintenance-free as possible. I'm near Shreveport, so my climate is very similar to yours. The only thing I can think of that may adversely affect a SWCG in your area is the possibility of hurricane damage--in that event you're still going to need to use lots of supplemental chlorine to clean up the mess, but bleach works well for that.
