I have the MSR Hubba and it functions well as a light weight solo tent. What I do not like about it is the colour, which is terrible for stealth camping and that it is not very comfortable for long periods of time such as getting caught in the rain for a day. Also the guy lines should be used to keep the rain out, not a big deal as there are only a few of them. I would agree with the recommendation to go with a 2 person tent.
