Thanks, I agree with your thoughts on the appeal of video for capturing the experience, it's most of why I've largely abandoned still photography. I'm just never going to spend any time with post processing hours of video, or want to duplicate the storage requirements, so I'm grateful for the camera FOV setting options of the newer GoPros. Just doing some quick testing from my desk when I got the Silver 4, it didn't look like Narrow was a great deal narrower than Wide but it clearly rectified the image (not that it was truly objectionable to begin with either). My main wish for GoPro all these years has been for them to make one with considerably narrower angle, or even better a zoom lens. The Narrow setting is not nearly that yet, but to me worth the image improvement. Most of my video is just reef cruising, some spearfishing, and I've always been disappointed at how distant everything looks with the fish eye lens. Fine for overall impression, and things that can't move away quickly, but not good for pleasing capture of most reef fish.
