I think the stuff sack option may not be a bad idea.
My 20* 3/4 zeppelin goes in very easily, however I have a 60" wide top quilt regular length rated for 20* and it's a bit tougher. I can get it in, but I'm almost afraid I'm going to rip the stuff sack Or that it's compressing the down a bit too much... of coarse it hasn't ripped and the down always fluffs up and keeps me toasty. The fear is just there.
Honestly, this is the only thing I can think of that I don't absolutely love about my quilts.
