Windshield vs. Fairing

[joe3407nomad]

I see many of the members with fairings on their bikes, I'm just wondering why so many do? This is my first bike with a windshield this big and it blocks out the wind to the point where it almost feels like I'm not even on a bike, I'm not complaining, its great but I'm wondering why a fairing. Doesn't the fairing kind of close you in? Does it obstruct your vision at all? I'm 6'1 so that's not an issue. I know it does looks nice on the bike. Any other issues that you might have noticed, as opposed to just the clear shield? Kinda looking for Pro's but really Con's
