I'm glad you've had such support and moved toward an aftermakert screen choice. For those who will follow this thread in the future, I will give my experience with a different item which I hesitated to mention. I opted for a screen made by Laminar Lip in a dark smoke tone. It is made from quality materials (nice and thick) and comes with longer mounting screws and small washers. As delivered, it is not prebent and is shaped as it is fastened to the fairing. It mounts over the stock screen, allowing for a gap between the two screens for venting wind to, I believe, decrease the pressure behind and smooth airflow somewhat. I say this after having a bike that came stock with a similar construction.
As for effectiveness, my experience has been that it has taken a measurable load of wind blast off my torso and I easily am comfortable at extra-legal speeds. I am keeping it and am satisfied for the unexpected comfort it adds to a naked bike. It also works well on the cold and can be ducked behind with just eyes above the screen at night for a very still pocket. Also, it may offer a wider area of protection than other screens: it has small wing-like side extensions adding breadth.
Now for some quailifications: this item does not make the T. a touring bike. There is still buffeting about the shoulders and sides of the torso that gets old on longer rides. The wind blast is moved to the very upper chest on me, a little below helmet level. I notice a profound difference in performance depending on wind conditions of the day. When the air is still or when headed into the blast, all is well. If the day is gusty, the performance of the screen is diminished. This probably is to be expected with any aftermarket screen. I am spoiled from experience with well faired bikes engineered to poke a smooth hole through the medium.
One irritating thing about this screen is, that as I sight down between the upper and lower, I see an asymmetry in the way the Laminar Lip arches over the old: one area is slightly higher than the other. I suspect this is due to it not being factory pre-bent.
Again, I've found that this has really made high speed work markedly more comfortable.
As a final note, there is always the aesthetics of a design, so, while I'm quite satisfied, you may hate the look (see my gallery for the item). One begins to move away from the look of a "naked bike" especially as screens are added. But, if you are fussy about tuning your air and are going to tour, there is one other possibility to consider which I used a long time ago on a big old brute high speed bike. There is a company named Saeng which for many decades have produced winglets that can be added to screens to smooth and adjust airflow. Here is a link for those interested:
