Carolina Lakes is a new public in Lancaster, SC, ten minutes from Ballantyne and built within the new Del Webb / Sun City retirement complex. Tim Freeland design, 7200 yards, ~$50. Played it once last fall (winter?) and loved the rolling greens and fairways and elevation changes between holes. Will play it again soon.
Palisades is a ~2 year old private course but might not get much play and is worth checking out if you can get on. Nicklaus design (but not Signature), so a junior there probably had a lot to do with the design, which includes several thought- provoking options off the tee and into the greens.
I still enjoy Birkdale (Palmer/Seay) and Skybrook (?) occassionally, and of course Mr. Doak's self- proclaimed worse course is here, Charlotte Golf Links. And while Charlotte National is not kept in very good shape, those enjoying fast and firm and some interesting holes might find it interesting, esp. in the ~$35 range for off- hours.
