Since you're still in the shopping phase, you might want to also look at the Big Agnes Emerald Mountain and Copper Spur models - functionally very similar to the Hubbas, but with a slightly better space arrangement. I've used the Hubba a fair amount, and liked it a lot, but I like the Copper Spur UL1 much better. In particular, it has a zippered opening so you can actually use the small rear vestibule.

How much will the rest of your load weigh? If you're staying fairly light on everything else, and particularly if you expect to spend some time tentbound due to bad weather, the extra weight might be a good thing to splurge on, and get the two-person version of whatever tent you decide suits your needs.
