PVC is really not a good cover. It's good for those who are on a tight budget and can't afford PUL or wool covers, but they aren't good because they don't breath.
What about the BBH did you find hard/confusing?
They have great pictures showing how to use them, which I found great. I actually find MCN so much easier than flats! No folding or snappying or pinning and such better containment!
