I just installed an aeroflow screen (not the madstad one) and this seems like an ok place to report... I got the Tall version and it's actually working really well. I'm about 6'4" tall, 33" inseam; 285lb. Long torso - former powerlifter, etc. I've got a low seat concepts seat on the bike (went low after doing to s spec suspension), and the screen is still on the short side for me. As I sit normally, the screen covers about 1 car length of my vision in front of my wheel, and past that I'm looking over the screen. So really it could be an inch higher I'd say and I'd still be fine. Even though it's a little short though, it works really great. The very top crown of my helmet is in some slightly turbulent air at high speed which puts a slight vibration on my helmet, but there is no major buffeting, and it's night and day better than when running with just the stock screen, which has always buffeted me pretty brutally. Anyway, I think it's a pretty sweet design the way it works in conjunction with the stock screen to channel air up and over. I'll be sticking with it!
