I have a Big Agnes Big Creek 30 degree double sleeping bag and it's really nice. It's designed so that you slide your sleeping pads into the sleeves at the bottom of the bag, so they don't move around on you.
My wife is always cold and used to bring a 0 degree bag for herself, even in the summer time. With two people heating this 30 degree bag, she says she sleeps warmer in this one than she does in her cold weather bag.
I'm a bit of a human furnace and very prone to overheating in my sleep, so I'm usually hanging half of myself outside the bag while she stays warm next to the other half. She loves it and says that she won't ever go camping again unless we're bringing the double bag.
I think if you're running a stove in a tent, you should be plenty warm in this one. They also make a 15 degree version of this bag that you can consider if you're prone to being cold at night.
As you can see, it's huge when it's all laid out, but packs down about 20% larger than my wife's synthetic 0 degree bag because there is no insulation in the bottom side of the bag.
