Devin-I would not get a smaller tent. You can find lighter ones, but the smaller they are, the less comfortable they are in bad weather. My winter tent is a fairly big two person tent and I use it alone. Unfortunately, it is heavy.

When I was touring in NZ years ago, I took a Sierra Design Flashlight (the old sleeve model). It was okay, but did not have a vestibule. Today, I wouldn't buy a tent without one if I knew I was going to be in rainy weather. Two people in my Flashlight was a squeeze. Don't be seduced into getting a bivy sack or something tiny just because of the weight. You will regret it in heavy weather.

I was at Lake Manapouri for a couple of days in really bad weather and luckily I was by myself. Two of us in the rain in the Flashlight was no fun as I found out later.
