I made a slight miscalculation — it’s more like 2.5 seats south of the Georgia Black Belt. So you could give Barrow and Kingston their own seats, and then let the new 8th wrap around the southwest corner — Quitman, Clay, and Stewart are Dem but only a few hundred votes — easily outweighed by Decatur, Grady, and Thomas. The new 2nd goes from 48% black and having to add 60K residents to 55% black, breaking few if any county lines, and nearly ideal population.
You can actually redistrict Bishop out as well. I prefer to do exactly that.
