The down does end up in one side of the "pockets" sometimes, how the are packed seems to make a difference.
The minus rating is a survival number not nice and warm at that temperature. If you are a high country camper and expect minus 3 or 5, get a minus 10 or 12 bag.
Talk to people in high end camping stores, if they sell climbing gear there's a good chance they know sleeping bags.
