minor thread steal, just because I definately don't need an HD version. anyway, I ski, surf and mountain bike and want to capture all three with POV video. So for the biking and skiing, I'll use a helmet mount probably, and for the surfing, a wrist attachment (just because I don't want to add a plug to my board). So with one camera to do all this, what is the best bet? I've heard wide angle is sick, but do I really need it? and also, is it cheaper to get the helmet mount/camera package and wrist mount seperately or the other way around? like basic wrist strap+camera and then get the helmet mount as an add-on?
