I've tried a few screens over the last 2 GS's....trial and error
I didn't want a massive screen
Including the MRA vario & Vario X creen, Z Technik, a cheap one from China (Which did work but the quality wasn't there optically and the finish wasn't good)
Went second hand for them all except the Z Technik one and the cheap Chinese one. £22 delivered
Now settled for a GSA clear screen which works great for me nearly all of the time
I did acquire a set of adjustable braces along the way with the big vario x creen which I left on. They reduce the wobble especially with the Puig attached. Once I found the best setting for me, I haven't adjusted them
I also bought the Puig 6320H after seeing one fitted to my mates KTM. He let me borrow it for a ride out. Amazon had them at £43 delivered earlier this year
Put the Puig extension on for the colder wetter weather. It works great at shifting the air and rain over. It hasn't marked the screen. I just set it at a jaunty angle but still at the same eye level as the screen.
What works for one doesn't mean it will work for another
5' 10", I have the BMW 25mm risers on
