Try the hand mount. Takes a little getting used to, but I can elminate the road noise and vid vibration, have all sorts of angle shots, including rear view, side view, and cool panning capability...wherever I point my hand. Going over bridges, I can reach out and point down and get a better sense of the climb over.
I adjust the strap so that I don't have to do a lot of maneuvering; sort of cocked to the side of my hand [looks funny, but works for me].

I'll try and post a sample here [gotta go ride right now]. BTW, I'm surprised I don't see more of these little gadgets at century events etc; they are great little cameras IMHO. I usually just use the bar mount on such event rides; less conspicuous that way [for personal use, memory etc, so I can live with the road noise and vibration etc just for my peruse].
