Just returned - plans changed.
We did Liberty Bell, Concord, Lexington, Mt. Formidable, and Mix-up and the D7's were money for all of them. What helped was having some Montbell puffy pants that I could dry my footbeds and socks in at night, and I dried the shoes some by sleeping on them in my bag. I'll use the same setup next time, maybe with better Sealskinz socks (I lost one so only had one for the whole trip, and it didn't seem to matter much). Thanks everyone!
