I find a 70/30 Cotton/Poly blend in a Percale weave are the way to go.

@Philip Mullinax I would think for sound proofing you would be looking at putting in some rock wool, either the insulation meant to go between joists, or the solid type.

Or a Q-Tip vs. cotton swab thing.

I am a contractor, shes knows i'm a contractor, so she cant try to pull wool over my eyes, shes not that type of person from what i know either. 

Cotton row and ascent trail are two spots with quads, I'd call them C class areas but trending in a positive direction.

As long as there are no leaks currently in the ponding spot, all you need done is to have that seam where the water ponds recoated with a 3 course patch of roof cement and cotton rag along the entire length of that seam.

What are the specifics here, @Malcolm Cotton?

Dull the finish with steel wool.  

Find where they are entering and plug the hole with steel wool (or wood, brick, etc).
