Scapegoat, what do you mean you are trying to "lower the point of contact" for your drywall?
completely off topic for this forum. but! we're putting a drywall ceiling in our basement. We screwed 2x3's to the floor joists so we could clear some piping for our baseboard heat. I also routed some channels for existing wiring which we'll also toss on some steel plates so we cant screw through it.
much easier than cutting and moving pipe and drilling through the joists.
