Really anybody who has experience would be great.

I looked at DensArmor paperless fiberglass mat drywall or just called yellow board at a Lowes; I've never noticed it until I needed to redo a bathroom. According to GP's website, this is an alternative to green board.

Besides the mold and water resistant claims, what are your experiences with it? I know they sell their own joint compound for "added mold protection", but I've still got a lot of regular compound; does it matter?

Any advice or experiences you care to pass along?
