Good Down South MC's?

Who are some good lyricists from the South? Are there any dope underground rappers out there a lot of us haven't heard of? No need to list Chamillionaire, Cunninlynguists, David Banner, Field Mob, Goodie Mob, Nappy Roots, OutKast, Scarface, UGK, Z-Ro, or anybody from Cash Money. I've heard all of them and have my opinions of their music figured out.
