Mounting gopro bracket on a helmet, how far forward / back to mount?

[Nick]

Sooooo the brain bucket came in today (Giro Seam), already got my AZ sticker on there, ready to attach the curved GoPro helmet mount. How far forward / back should you mount it, or does it not really matter? Looks like the space all the way from the stack vent up to the vent switch is pretty open for mounting.

Because of the adjustment knob on the GoPro's it doesn't really matter on the location. Unless you want to use the mount that looks back at your face, then you need to mount farther forward.
