I've had three different screens on my America. At 6'2", these are my impressions:
Triumph Roadster - looked good, a lot of buffeting (I had to switch.)
Triumph Tinted Flyscreen - looked great, minimal protection, some buffeting,
Windvest - neutral looks, fair protection, little to no buffeting
I sold the Roadster Screen and Flyscreen... I kept the Windvest.
