I have the GP and I love it. I shoot mostly from the helmet mount. I have done Chest mount but I don't like it as much on the bike. I want to be able to aim the camera where I want. The chest is good for watching your arms, computer, etc up front but unless any action you NEED to capture isn't directly in front of you then it is useless.


Here is a demo of how I have it mounted in the bar and helmet config and a shot clip of vids showing each position.
