I've always used the stuff sack a sleeping bag comes or a dry bag with for my sleeping bag when I'm packing, but since I have joined WB I have noticed that many people just stuff their sleeping bag at the bottom of their pack. I tried this with my EE 10F down quilt and Zpacks Arc Haul since both are new to me, but trying this method seems to take up a huge amount of room and I can't get everything else in my pack. It seems to me that there is too much air in the quilt, but I can't compress it enough in the pack to reduce the volume for the rest of my gear.

Is there something I'm doing wrong, or should I resign myself to using my normal method?
