Modular flip face... all the time, just prefer the full face protection. Nolan N103.
I look through the windshield, I would prefer to look over it, but I'm not tall enough to do it with the shield all the way down, the top of the shield line is right in my line of sight.... so I raised it a few notches. Works fine.
But, in serious rain, I do have to drop it and sit up and look over the windshield...
I have found that riding it with the shield down results in a lot more buffeting of my head... with the shield raised a little, the airstream clearly goes over my helmet... making a smoother ride for me...
