I'm not in the south either, but last summer we had several days in a row with temperatures over 90 deg F. The AC finally started on the fourth day because it took that long for the house to heat up. We do not have any radiant barriers, but do have 32 inches of insulation in the attic.

A radiant barrier is better than nothing, and plenty of insulation is much better than any radiant barrier.
