I decided to take a "why not both" approach. Purchased the wanderlust kit which will be my base for solo and am going to rent a 3" insulated pad from REI for the next trip. The wife can try them both and see which setup she would prefer for a 6 day trip, assuming I can stand sleeping on the ground again myself, then will kit out from there. I prefer spending the stimulus money on gear than on paying for more rotator cuff surgery, so probably going to end up with 2 hammocks.
