You could try adding another piece of flexwatt on the cold side. But the ambients need to be up too. I shoot for 92 to 94 and 82 to 84 with an ambient of 82 degrees.
As far as the SC deal. Maybe she meant that its on the opposite end of the country? I've never been to South or North Carolina. I hear there's some good scenery though. I work with a lot of bike riders that have been through there.
I don't think she meant SC would be a bad place to live.
