Clearview
Shrek, in case you are still wonderin about the Clearview, I have the tallest one and I really like mine. I don't think the vent does any good unless you still want bugs in your teeth. It is also a pain in the keester to clean around, which would obviously bother a meticulous rider like you. I would leave that off next time but I got a deal on a scratch and dent model.
As far as the screen staying on, no problem. I burned a tank of fuel heading to Sturgis in 100 miles at "highway speeds" or far north of a buck twenty, yes 20mpg and she stayed on.
The lowers are a big help to me in reducing buffeting, took them off last summer for one ride and put them back on.
