|I liked that the Rikkis did fit a bit more trimly, but grew to dislike them for the reasons you mention, that, and the guessing about whether the fit was right. With the AFs, just snap, snap (snap, snap) and you know it's right and not rubbing. Eventually, DH, who has always been completely on board with CDing, refused to use the Rikkis, and I sold them and replaced them with AFs.
That being said, I can see that the XS Rikkis could be great with prefolds for a trim fit. If you decide to sell them, you'll obviously not be able to sell them for quite what you paid, but if you explain that they're basically new, you could probably still get a fair chunk of it.
