I forgot to post after I got my last batch of GIK of panels. They made a huge difference as I finally got one up on the first reflection point on the ceiling. I had a bit of upper mid glare that had me considering a new pre-amp, but this solved that issue. Soundstage width and depth are getting better too.
Again, I don't think I could DIY them for much less money, (even w/ the upgraded fabric choice) or do nearly as nice of a job. Plus fast shipping on even custom items. Hope to mix in a some diffusion panels at some point to what that does, especially on soundstage.
I wish you continued success. You deserve it.

I have become a complete believer in the idea that the room is part of the system, and must be addressed.
