I got the head mount and chest mount. Don't like how the head mount gives no sense of depth, can be cool if you're following someone though. I like the chest strap, because you can get the bars in the picture. However a few things a picked up with the chest mount: 1: Need to mount in upside down mode 2. Need to make sure the mount is as tight as possible 3. I found in normal wide angle (170) it was too wide, and got my whole arms in the picture, and it just looks weird. Have to experiment with a less of wide angle 4. Tighten the gopro to the mount PROPERLY, or you may get to the bottom of run with some nice footage of your manhood jiggling around down the trail! Never tried a bar mount as I've heard that they're just bumpy footage? Can someone post a link to a video with your K-edge mount?
