I might be pointing out the obvious here, but I cant help but notice you didn't mention Western Mountaineering.
The Badger and Kodiak are both offered in a 7'0 length and are cut wide. The Badger is 2 lbs 10 oz in 7'0 length. They also have a Sequoia if you want an extra wide cut.... and it still weighs 3/4 of a lb less than a wide/long Slick bag (stated specs, not first hand experience).
I have a Badger and love it as I am also an active sleeper. I have extra fill in mine and have had it below zero with no issues. I used to think I was a cold sleeper - I just realized most bags suck and their stated lower limit rating is BS. I can sleep in my WM comfortably below its stated rating. By all accounts FF is the same, but I don't have first hand experience.
