I filmed last weekend for 3 days straight, 6-7 hours a day of riding. I had a Pole Mount, Helmet Mount, and held it in my hand.
In my opinion, pole mount trumps all. Follow footage is excellent because you can stay a bit back but get the close up you want. Self shots end up looking great. It's just a nice way to go about it. The downside to the pole is the weight. I have a Go-Pole and found it to be heavy the first day of riding. By day 3 I was used to it and I didn't think about it anymore.
Take it all with a grain of salt. Everyone has their preference.
If you want to be a chick, a dude, a tent, or a velociraptor be my guest, but if you choose the last one you bet your ass I will have a spaz-12 to your face.
