I bought the Cee Bailey's +4/+2 a month after bringing the bike home last summer. It was fine. A noted improvement for me over the stock screen. (6' even and 30" inseam)
I ran this all winter, rode through the 20's and it was fine. Even in 100+ degrees, it allowed enough cooling air when down to be comfortable around town.
I was always hunting for the sweet spot in regards to wind noise, though. There is a sweet spot, but it obviously varies with road speed.
Then I started experimenting with different hearing protection options to limit wind noise. I found some 33 db reduction el cheapo disposable foamies that were the ticket. Suddenly I was very happy with my combo.
Then I caught a mild case of farkleitis and ordered a V-Stream, figuring the price was good and I could just resell it if need be.
WOW! What a dramatic difference (for me) over the Cee Bailey's!
Less back pressue on my, ah... back, when up. Shorter overall height, so when down my helmet is in clean air (quieter) and the wind blast lands nicely on my upper chest/shoulders. That said, you can obviously fine tune this wind blast effect by positioning the screen up or down to your liking.
I can say that wind noise, overall (in all positions) is less with the Vstream than with the Cee Bailey's. I suspect this is due to my Cee Bailey's having the "flip", which I'm guessing makes the air tumble a bit more over the top.
My wife also noted a difference between the screens - she feels the V-Stream is a bit more comfortable and quieter from the pillion.
Obviously, your results WILL vary. Getting your bike set up comfortably for you is a quest. one in which only so much of the available information is useful. Ultimately, you need to step up, buy things and try things. It's always smart to seek opinions prior to laying down the dracma, but in the end, no one else's experiences and set ups will be perfect for you.
Also, beware - if you find your ideal windscreen, then next year buy an aftermarket seat, this might upset your ideal world due to an increased seat height.
Such is the battle of customizing a bike to your own back side...
