I come from a background of scouting where the emphasis is on the group. Therefore, I suggest you consider a two (or even three) person tent to share, providing that you think you can get along with your hiking partner for 8 day 24 hours a day. As you have noted, it will be lighter this way and you have the opportunity to work together. If, however, you think you need time apart from your hiking partner, get a Henry Shires Tarp Tent for the space and light weight or a hammock for the joy of comfortable sleep.
