Allrighty, some weeks done with this screen now.
The plus-side:
- Improved weather protection. On of my main objectives now OK.
- Good looks. Blends nicely with the 800GS design IMHO.
- Easy bolt-on-job done in 10-15 mins.
The minus:
- Severe buffeting requiring ear plugs. I mean vicious, loud buffeting noises here. We're talking dangerously loud buffeting with ear-damaging potensial.
- I'm 1,86m tall and recommend usage of ear plugs at all times with this screen. Even then you'll get a steady, vibrating bass-drum droning noise which may feel uncomfortable for many people. But at least you don't feel knackered after a multi-hour ride with ear plugs in place.
Since my first priority was weather protection and style, I'll fabricate some home-made winglets and try a screen extender. There was a noticeable reduction in wind noise when holding my palm down at the left side winglet area.
If this prototyping doesn't work OK I'll simply buy a pair of winglets from
Nippy Norman:

But be warned; the Wunderlich Ergo Screen Hoch is dangerously noisy and its Decibel levels/noise ratio requires wearing ear plugs at all times - depending on your personal height, of course. Btw, I use a Schuberth C2 helmet. Not exactly a noisy lid.
Conclusion:
This screen does not work on its own without noise-reducing measures. According to Norwegian law at work places this screen produces dangerously loud wind turbulence noise and will damage your hearing if ear protection is not used - as goes for most motorcycle helmets - depending on the rider height/fairing combo.
Recommendations:
I recommend
Nippy Norman winglets, screen extender and ear plugs as possible noise-reduction tools for this screen for a rider near 186cm tall. Your personal height and your helmet's inherent noise-dampening abilities will of course influence this appropriately.
