When I bought a GoPro Hero3 camera some while ago, it came with a bundle of mounts which I have been experimenting with when out cycling.
I started with the GoPro handlebar mount.
After a few outings with this set up I became increasingly concerned with the stability (and security) of this arrangement. It seemed to do little to dampen the vibration transmitted through the front fork when travelling over rough ground. I looked around for an alternative and settled on the k edge.
