I used and loved my Big Agnes Fly Creek 1 man tent on my AT hike. It fit all my gear just fine. You don't have that much gear. It's very light. It's just you anyway! And the shape of it allows you to tuck the back end into corners and bushes when there's no good open space. Keep that thing! Loose that heavy 2 person tent, get a refund, or save it for car camping. But you'll never lug it around on the AT past your first hostel stop, in my opinion.
