Yeah man, it's a tough one. If you have it attached to your marker you have to try not to point it at the ground so much or wave it around when you run. On your mask it's gonna stick out a bit. And on your shoulder your only gonna get one side. Ideally you want the 8ft pole from your back, up and away so the video looks like a 3rd person gameShoulder cam maybe?
I'll work something out, hehe
