I dunno guys. I bought this one

The screen is light tint and it looks great on my white GS.
(pic near the Lecht in Scotland last Sunday morning)
Putting a ADV screen on a "normal" GS is about 4.4cm higher and quite a bit wider. It has given what I need (I am 6'1")... went up the M6 to Scotland last Friday, if i lean forwards ever so slightly I am in completely still air, so I can hear the engine. I get hardly any bugs on the helmet visor. A bigger screen (for me) does not work, as I feel i am sitting in the bike rather than on the bike (makes me less confident cornering). One interesting thing, the back of my neck got damp when it rained! Otherwise great weather protection. In the pic above, the screen is about 50% of the adjustment - it does go higher.
Quality was spot-on. I have cleaned it (not too carefully) a couple of times, and it's showing no signs of damage.
The plastic was a bit heavier than standard BMW (screen seems slightly thicker), and I installed a Cymarc kit to stop any vibrations.
Very pleased. Good service, prompt delivery. Great prices. British. What's not to like?
