I have the Calsci mid size screen for my 2v 2008 Norge and am very happy with it. Then again, I have several screens and switch according to the season and purpose (i.e., long rides, summer in the city, etc.).
I also had a screen from Calsci for a V-Strom 1000 I used to own (wretch - it died after just 140,000 miles!). I would buy from Mark again.
