the helmet hero kit is good for riding and other stuff. the helmet hero pro kit comes with an attachment to mount it onto a vented helmet (think bicycle/snowboard helmet), a head strap/thong for say rock climbing, and then three mounting pieces with UBER strong 3m adhesive (one flat, one curved, one slightly more curved), a 2 piece arm that bends for a 90* angle. I didn't like the idea of how the camera would look hanging off the side of my helmet and I think it'd be weird on top, so I went with the motorsports mount. You can still use just the 3m adhesive stuff, but that sh*t STICKS. It took some paint off my home painted front fender-strong. (could've been my newb rattle can skills and not enough clear coat)
