I have the 2011 "X" model and I really liked the look of the stock screen. Unfortunately though, at a lowly 5'7" I suffered badly from buffeting and wind noise generally. I first put a Madstad on and, although there was a bit of an improvement, I still couldn't cope without earplugs. I've just put the MRA Vario-touring on [as well as leaving the Madstad on] and it's a revelation. I can now run it up to 70-80mph without plugs. Excellent! The only down-side is the look. The MRA isn't the most aesthetically pleasing farkle you can put on but Hello, the bike is my all-weather, any time ride, so looks are less important than max comfort. I haven't put the MRA on without the Madstad, so I can't vouch for the end result on the stock fittings.
Cheers, Steve
