Paintball Camera Gun Mounted Action cam advice anyone?

[splatbeast]

I am currently testing a couple of helmet cameras (action camera) for picking up footage on our paintball battle meets.
One of them is an Adrenaline Systems paintball cam which I have heard plently of positive stuff. Any advice i should follow to make sure the specs are good and it is worth keeping?

One of the cams has is CCD and the other a SD card unit. Any suggestions?

I will post what I find out after this week when I have had a chance to test them out. Any feedback will be appreciated.
