I've never experienced Centipedegrass. Do you get Santa Ana Bermuda? It's an old one here, but still a great choice. I don't know if you get Kikuyugrass there, but here it's just about the toughest there is. It used to be considered a noxious weed that was quarantined but they finally just gave up controlling it. It's only garden and pasture-invasive and not a threat to undisturbed areas.
