having used both get the gopro its easier in many ways such as changing camera modes, editing mainly, and its far more waterproof, etc. as far as the mounting, i wouldn't recommend the head lamp it is awkward and slips off easily, especially in crashes. you could use it but i personally just wouldn't. its too much trouble for not even stable video. get a handle bar/seat post mount and put it on your pole as close to the grip as possible and it'll work great, but obviously its not on your head. if you really don't want to wear a helmet for proper mounting get the chest mount harness. again obviously not the same as if it were on your head but unique, and stable footage. or the simplest solution would be wear a helmet for the best mounting, protecting you brain comes second, right?
