"What I am looking for, is no buffeting or added noise around the helmet, minimal turbulence in the abdomen area, and relief from headwinds."
You'll need a tall windshield for that. A quarter fairing won't do squat if those are your goals. I have a V100 Mandello that has the adjustable windscreen, and installed a larger tinted windscreen. With the stock and taller windscreen, raising it increased the buffeting around my helmet, so I leave it in the lowest position. I'd definitely stick to the big and tall windshield for what you're looking for.
That's what I liked about the Parabellum, waiting to hear if it will fit the V9, but unlikely since it is not listed on their site.
Best screen I have ever sat behind was a National Cycle Beaded Heavy Duty fitted to my Kawasaki Vulcan 800A. It gave protection from the top of my shins to the top of my helmet, and apart from some turbulence around my lap there was virtually windstill behind the screen. But the same model worked miserably on my Intruder 1400 and my Virago 750, because it could not be tilted back enough. This created a massive turbulence around my helmet that was almost deafening at speed. I managed to lay it back more on my 650 Dragstar, but failed to find a position where it did not cause noise.
The Windjammer V was also good, and the touring screen on my 650 Deauville as well.
