I've owned a seek outside for about 8 years (LBO w/ tarp & vestibule). I can honestly tell you that there isn't a situation in my mind where I'd regret the additional 12oz in my back for that much more space. There have been several times when running a smaller shelter has been regretful. I like a bit of space, and if the weather turns for a couple of days, being able to lay out or hang up gear to dry, have extra room for wood, etc, has done wonders for my psyche. If you gotta shave 12oz, get lighter tent stakes, or something else, imho.
I'm 6' & 220#. When I need to cut weight, I start with my gut. If I get another seek outside, I'll likely go with the Cimarron or maybe their new Twilight without the floor for solo trips.
