I've done a lot of head cam video and it's true that you need to cut away stuff, but you can get some amazing shots now and then. I managed to capture a nice pitch pole with a Hobie 16 a couple of years ago. The camera is ok to mount with a head strap and I had the dv cam inside the dry suit. I added a gps overlay box later on which put speed and course on the video in real time.
