The chesty mount is an issue given your chest position on a road bike. I'm surprised that it was shaking so much for you. I found far less shake with the chest mount then with the handle bar mount. You may just need to tighten up the straps. You can put it on pretty tight with the elastic. I broke my handle bar mount twice now. The plastic arm snapped. The camera is a pretty heavy weight on a relatively thin plastic stick. What works well with the chesty is mounting it on your back and filming the riders behind you, or cars for that matter. This video has the handle bar and chest mounts pointing both forward and back. I like how the back mounted, where you see the rider behind you, came out.:


Today I decided to try out time lapse video on the Go Pro and it worked out better than I expected (Blog post with editing software and other detail: Time Lapse Video)


I have the helmet mount but haven't tried it yet. I figure I'll look like a Teletubbie with it on my head:
