From what I've found out the GoPro has really good mounting options, because it can go on your helmet, or strap to your head or there is even a chest mount
But then the Contour has a better head mount, is slightly easier to use, and if you wanted to spend a little more you could even go for the version with GPS, so you would have an exact record of where anything happened, but then you could probably see that from the footage, so I'm a bit torn
