That would work fine for me but I doubt that I will have very many trips where I'm alone. I think the vast majority of my trips will at least be with my son so I've been looking at 3 person tents but they get even heavier. My list leader right now is the REI Quarter Dome Plus 2 person tent. It seems to be a pretty good balance of size/weight and I guess it's not terribly expensive compared to some of the others that meet my criteria.
