Looks like an excellent trip; glad you enjoyed it! A Superfly like yours is on my list when I get some tax refund dollars from Uncle Sam. Looks like just the ticket for cold-eather hammocking.
I do solo trips regularly. For me, the most important thing is to bring enough reading material. I went on a five-day solo trip late in the fall once and only brought one book and a portable radio. The weather turned bad and I read the whole book the first day and night. All I could get on the little radio was a Vermont public radio station and I had my fill of that after a few hours. I ended up packing up after a couple of nights and heading home out of sheer boredom.
On another trip, I made the mistake of bringing a Hemingway novel with a depressing ending (surprise!) and it took me a whole day to cheer up. ;-)
I live north of you a bit in Whitehall. I get down your way once in a while during trout season to fly fish the Battenkill around Cambridge/Shushan. A beautiful area.
Take it easy,
