I chose "every time"
I have my gopro on my bike 100% but I don't record all that much. I have it on there for just in case situations or to catch my son doing funny or whatever.
I do record all my fun rides/events just because you never know what your going to see but yeah I don't think I have ever created a video that was just so awesome I had to show everybody. I have some on my youtube channel to show family from out of state but nothing really just "epic". I did have a deer jump across my trail once that was pretty cool.
When my gopro does puke out on me I wouldn't buy another one. Just not worth the money for me anyways. Gopro stuff is nice though, mine has been an excellent camera.
