Lol... One cam is enough. Just want to set it and forget it. Edit it later. I don't see how a static helmet cam works on a snowboarder when the head is turning so drastically.
Seems like a board mount or lower leg mount would be more static and orientated the right direction no matter what the upper body is doing.
I figure it's trial and error, which a lot of people on here should have experience with.
You're right on the helmet mount though, that's all I ever see a side from the pole mount.
