Check out the screens from twistedthrottle.com (don't remember if address is small or large case but that should be close). I have their Touring Vario Screen made by MRA (made in Germany I think) and I love it. It has an air foil on top of it that is adjustable to 7 or 8 different positions. When all the way up it works great to take the wind off my chest and let me relax my grip, arms and shoulders. With it all the way up the wind hits at about the top of my helmet visor and I do get more wind noise, but that's what you'd expect as Windblown said due to the increased wash from any larger screen. I'm 5'10" and have Heli bars on my Sprint. When all the way down I don't think it looks too obtrusive cosmetically. I'll sacrifice a little curb appeal for dramatically improved comfort while touring. Just my opinion.
P.S. When I ordered the screen last September for my '02 Sprint ST, MRA wasn't making screens for the new '05-'06 Sprints yet. But the guy I talked to at twistedthrottle.com said that they were supposed to be coming out sometime hopefully early in '06. If I remember right, mine cost $140.00.
