I mean, hard to say but what I can tell you is CLT controllers are usually great to work with. if you want to transition over CLT, just ask for 4,500 or more and it's usually a no-brainer. CLT can get busy at times so have a 'remain clear of bravo' plan ready. otherwise, pretty straight forward. if you are going to fly into concord regional (JQF) definitely check the map for towers. there are quite a few tall towers in the surrounding area.
