Played with my screen angle and height for the smoothest position for wind @ my helmet. I tried alot of variations as the robo-brackets move every way possible.
In the end, I raised it some and angled it back a bit more that the 60 degree Madstad talks about. The bottom is more open for air to pass underneath too and this makes it very nice going down the road. Having a vstrom and madstad bracket, it's also the same bottom open angle that works on that bike too. it may look a little funny but sure does it work well.
Nothing but calm air on my chest and head. Of course there is air leaking in from the side but it's not a goldwing. If you spend alot of time on paved roads with your DR this might be the ideal screen solution. I can see over it just fine for off-road work and the whole bracket / screen can come off quickly with 4 bolts/nuts if need be. (update: changed over to thumb nuts so I can do this by hand in minutes)
