Hi Diva,
I perfer to use a Breathable inner and DWR outer on 20* and up quilts, condensation isn't as much of an issue but winter setup I use full DWR shells to help keep moisture out of the quilt. DWR on outer help with minor misting and tarp splash back. One negative to a full DWR shell is slightly longer loft time as well as tougher to stuff into stuff sack. This is due to DWR finish not allowing air to move through the fabric as well as a breathable fabric.
I usually don't use a DWR when in contact with skin just due to the feel of DWR on bare skin.... I assume we are talking about 1.1 RS fabrics here as I know the M90, M50, 8d, & 7d DWR fabrics have a softer feel...
So, basically I'm sure I just added to the confusion....
In a nutshell full DWR shell is OK as long as you understand the minor negatives...
