i tried, and failed. have you ever followed camed down a narly mountain? its damn near impossible and sucide to be hauling enough to follow down a big mountain line while looking at a little camera screen.
i know what your saying tho. i also tried filming a line from above, but it was so steep you could only see them hear and there, and i did throw a few seconds of that in near the beginning. but a working tripod and more zoomed in would have been better.
thanks and +karma
