metal or wood studs?
DUDE, I've hung A LOT of drywall on metal and never had a problem. Even 2 layers of 5/8" overhead (that's a lot of weight). I see your thinking, but the application works as designed........no worries. The inherent problems are the same as with wood. Water intrusion, 'ya got a problem and it could come down. Someone steps on the board from above in the attic, it's coming down. Not just under it's own weight though. Again, adhesive certainly won't hurt.
