Thanks Robb,

Sorry I haven't responded earlier, I've been out of town. I think I will drop the RC on the walls and use RCIS-1 on the ceiling, cover all walls and ceiling with 2 layers of sheetrook and GG. I've seen some people suggest that 1/2 + 5/8 is superior to 2 layers of 5/8, any opinions. If I understand the argument, 1/2+5/8 will minimize the potental for ressonance between the rock. Doesn't the GG deal with this issue? ALso does anyone see any benefit in putting MLV on the ceiling before I install the RCIS-1 brackets (in addition to using GG)?

I'm a little troubles by the door. I'm planning on using a solid core (steel covered) exterior grade door with a threshold and seal. Do I just install it in one wall (e.g., the interior wall)? What should I do about the door jam between the two walls to avoid creating a hard connection? I realize that two communicating doors is a better option, but I think this is an impossible sale to the wife.
