Basement Insulation: Kraft or unfaced insulation?

I live in the upper Midwest and am finishing my basement. It is a walkout and the part that is above grade is insulated with a vapor barrier. I have been advised that the below grade portion should be insulated with unfaced batt insulation so there can be air movement, while others have told me the exact opposite and that the kraft paper faced insulation will still allow it to breathe enough that I won't have moisture, ie mold problems. Any answers out there? I already have put up the kraft faced insulation and if need be will take it all down or maybe just cut slits into it.

Kraft paper is not a VB. so it will not trap moisture. But the paper will suport mold growth. Id go unfaced.
