I'm curious where what mounting locations and mounts (double sided 3M or Suction) you are using for your POV cameras. I'm debating on whether to mount it on my helmet or the bike itself. I'm really resistant to sticking a mount on the bike so the suction option makes sense if it actually works. I can't tell you how many times I've had a gps window mount fall after a short period of time from squeaky clean glass.

If you are mounting it on your helmet, how noticeable is the wind noise and is there any noticeable pull on your helmet?

I'm looking to purchase a Hero 3.
