I found your question and the comments interesting. I have only made a few quilts and I have not liked the back where the seam is from joining the two widths of fabric. This is because I just do SID for now and you really notice the backing seam when it doesn't align with a the stitching of a seam on the quilt front. On my last quilt, I took the time to pin and then baste so it did. Wasn't easy but I like it better. I think I will be looking into wide backings, however! I agree that QAYG would be the way to go.
