I use a Drift. Had it stuck on my head, was cool...and then I mounted it to my bike's handle bar. Camera on the helmet is annoying (video moves around during playback, more difficult access to controls, wind resistance and wind noise..yes, the smallest gap will cause a "whistle").
I would have preferred to put it on my chin but the helmet doesn't allow for it without possibly losing hte camera.
I'm still experimenting as I got the camera for free so just testing it out.
There is a little wind drag but nothing crazy. Where it's mounted doesn't add any noise though.
If my phone wasn't on iOS10 I would have just used that to make sure I'm recording, but in this case not even that would help.
I was inclined to put the camera on the bike but that means it doesn't look where I look so you'll make for one boring video.
