unless you've already hiked the whole AT - including the VT section, (like 10K has) I would strongly suggest going NOBO - the trail sets up so well that way - the further you go, the better the scenery, and the harder the hiking - the hiking starting off isn't "easy" but it's a good warm-up. Going SOBO would have been anticlimactic to me (and I had already hiked the southern sections long ago on my thru).
