Hi,
a bit late perhaps, but here it is : a Wunderlich Xtreme screen mounted on my R1200GS. Went to the store in Germany to test both (Ergo and Xtreme) screens. There's a nice stretch of highway, and the folks at Wunderlich are swell and let you testdrive both versions. The Ergoscreen is awfully big, and didn't stop the buffeting around my head, so I tried the Xtreme, and have been using it ever since.
