I am now all 100% for a good aluminum mount. I used the plastic mounts from Go Pro and one snapped on a 40 mile descent, bounced about 50 yards. Luckily the road was straight so I was able to retrieve the camera in it's case. But the mount prongs sheared. I dislike the plastic Go Pro mount prongs as one must crank down on the screws to keep the camera steady.

I invested in alum mounts ( K edge) but it was well worth it.

Not sure of they have alum camera mounts.

But I also use a tether now to avoid it from actually falling and hitting the ground. I use old camera wrist straps, I thread the small section that usually threads into the camera fixture, into the hinged are of the go pro case. Then I wrap around my bars etc lasso style before mounting. That way if it falls, it dangles from the bike instead of hitting the road.
