Thanks for your comment on my "gnarly bike tire" status. I have thought about a helmet cam. The GoPro Silver appears to be ideal.
I actually rarely wipe out. I ride 100's of miles in a week without mishap. However, when I do make "unplanned dismount" the results are spectacular.
I tend to do a lot better are difficult terrain when I am fully engaged. The majority of my wipeouts are on relatively easy trails. This holds true when I am skiing as well.
Thanks for your nice comment on my "Rookie Mistakes" blog. I consider elbow and knee protection a bare minimum for mountain biking.
The 661 pads are very high quality. I use these pads for easy trails. I have some Fox elbow/forearm and knee/shin armor for more difficult terrain.
My full Robocop armor includes a chest protector and padded shorts. I use full armor on difficult technical trails. I may start using full armor protection more.
I have full face bike helmet that I wear when I am trying new techniques. I am trying to keep the battering of my body to a minimum.
