I have an Aeroflow and love it - and I'm sorry, you can't have it to try.

(I live halfway across the nation from you)
It's not simply longer, but also has a subtle curvature at the top edge - a 'flip' that mimics the rear spoiler on a NASCAR. It does a nice job of keeping the airflow smooth and over your head versus tumbling down on top of it.
And notice I didn't say 'taller'? The nicest thing about having a longer windshield on a R11050RT is the fact you can leave it in a lower position and still be effective. That lower position is much less upright too - so your profile isn't like trying to force a brick through the air at 70+ mph. With the stock shield, I had ti have it almost vertical to 'fit' me - and it basically just stalled the air and let it come crashing down ontop of my helmet
