14 lbs seems like a lot for a march start on the AT. You have a lot of light/quality gear - I would just focus on trimming down how much stuff you actually are bringing. For example maybe not bring the flip flops, leatherman, extra mug, two shirts, a towel, etc etc. Of course this is easy stuff to ditch later on if you want.
This would partially be to save weigh but also just to have less crap to have to keep track of. Personally, during a thru, minimizing how much assorted junk I'm carrying makes hiking more pleasant.
