Figured I'd add a few pics of my Spitfire for comparison. The only gripe I have about it is the mounting brackets. However, with patience and trial & error, its not terribly difficult to find a good mounting spot - even with a SE bar, crossbar and all.
The height of it as shown keeps all the wind pressure off my chest and redirects it just at the neck/shoulder level, leaving my helmet in clean air, no buffeting.
I also installed a National Cycle Deflector screen on my wife's DRZ-SM. Exactly the same fairing, so this will work much the same on a DR, as well.
Again, the only downside is the bar mount. The added versatility of the pivot-mounts on the windscreen allows you to be a little more creative as to how and where exactly you mount this screen.
