I bought the LCDback and love it. Really makes the GoPro more usable.
Here's what I managed to do during my autox last weekend. This was my fourth run and I was getting frustrated that my buddy kept throwing down incredible times. I figured I'd 'go for it' and this was near the top of 2nd gear. the car started to drift but it felt very controllable so I figured 'what the hell, ride it out'. Well, a very slow slalom was fast approaching and I couldn't get out of the drift without screwing it all up. Ended up holding my corrections too long. One might argue I was distracted by the giddy laughter of my passenger!
Second video is of the most incredible save (obviously not me). I watch it over and over...mesmerizing and something to strive for.
