Diggin the helmet mount and front bumper mount. I contemplated the rear bumper mount, but after seeing too much rear end in the vid I think it would only be worth it to have a tripod style mount to elevate it quite a bit higher and utilize the panoramic capability of the camera. The handlebar mount was trippy due to counter-steer. Pointed one way, going the other. Wasn't a bad perspective, but maybe chest mount is the way to go.
I am going to test out the suction mount on the gauges since it's a flat, sturdy surface and see how that holds up. I have had it mounted for a couple rides without the camera and had zero issues, but we'll see how it does with the camera hooked up. I would also like to put a mount right behind the seat and have the camera pointing backwards to get some footage. Just worried it would get kick at some point moving back and forth on the sled.
