Tracking Room Ceiling Question

[SMC Productions]

I'm finishing up my new Tracking Room, and have a question about the ceiling. The room has 13 foot ceilings, to start. I have lots of 703 panels, and VERY thick corner treatments so far, and the room sounds pretty sweet already.

The ceiling is 'made' from 7/16 OSB, with R19 insulation on top, and 2x6 'exposed' beams for frames underneath. I want to fill in the 'exposed 2x6 frame with another layer of R19 and use again the 7/16 OSB for a 'finished' ceiling.
Now to the question, as you have the background. Should I 'strip' the paper vapor barrier off the R19? Should I just use 1x slats, instead of the OSB and space them for added treatment?

TNX in advance!

It depends on where that fiberglass is in relation to the microphones and the things you'll be miking. The paper facing reflects high frequencies, so it's not good if it's within, say, 5 to 10 feet from a sound source or a microphone. For those nearby surfaces you should remove the paper or flip it around so the paper is away from the room. The main issue here is avoiding comb filtering.
