QD 70/30 is my standard batting...I keep a large roll on hand at all times and use it for almost every project. It does not need to be closely quilted if you have a quick project, is very easy to handle, washes and wears extremely well, etc. I also like its weight (not overly heavy or too warm for here in Florida). However, if you are looking for a batting with higher loft to accentuate stitching and stand up to laundering, I think you need to go with much more poly or perhaps wool, although I have not used the wool. QD 70/30 is not very high loft.
