I spent a lot of cash "trying out" other screens. I tried pretty much every screen option on my GT. CalSci, Vstream, several different Cee Bailey sizes, etc.
I'd have been happier and spent much less if I'd just have gone with Aeroflow in the first place. It just flat works. Nothing but clean, quiet air, such that I can actually run it much lower than the other options and still be comfortable. Well over 100K miles later, I still feel that way.
The AeroGards add to the cost, but they offer two main improvements. Without them, the skinny GT fairing allowed a lot of wind and bugs all up my arms. With them, no more bug-arms. And with them, I can keep my mesh gloves on down to about 50į before I'm looking at swapping them out.
After you put a couple thousand miles on this setup, you'll have forgotten how much it costs . . .
If you prefer a smaller screen that's closer to stock shape but still works much better, then a CalSci screen might be what you're after. It's closer to stock size, but with a much better curve and a small cutout that really minimizes turbulence and noise.
So if you want a sleek, sporty GT (and ride mostly solo), then go with a CalSci screen (much better wind management in a near-stock size and shape). But if you want real protection for the elements (as does your passenger), just go with the AeroFlow and AeroGards. Yes, they're expensive, but they flat work.
Hell, if money was the top concern here, we'd all be riding the Original ZG-1000 Concours bikes, or maybe a slightly-used FJR.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...
