here's my $.02...
I'm regular and mount it on the right side of my helmet. I kept moving it back enough so it wouldcatch less of my helmet and goggles.
As far as mount goes, here's what I'm doing...
Profile mount + 3m dual lock velcro linky
remove the 3m sticky from the profile mount and replace with the dual lock
figure out where you're going to mount the camera
put the other side of the dual lock on your helmet. cut it so its the same shape as the profile mount. that way, when you mount it, you get the same angle every time.
The reason i do this is for crashes. earlier in the year, i just had the profile mount stuck directly to my helmet. But, i crashed and rolled a bit and the camera got knocked off along with the profile mount. This was on the first run of the day so I wasn't able to get any pov video at all. I've crashed at least once since using the dual lock and the camera got knocked off. I snapped it back on and continued taking video. Actually, this video was taken that same day after the crash.

ps, make sure to use the leash. I almost lost mine one day because i didn't. It was a pow day and i was fortunate that it didn't get buried.
