Snuck off to the Prom today. Barely a breath of wind, quite sunny, and fun, small waves. Tried the GoPro in a new position - clipped on the neck of my wetsuit. Better than the nose of the board, but not as good (but less conspicuous than) mouth mount. It is hard to see the board most the time, and not at all going left. Used
getxclear.com/ to keep drips off the lens - worked well. (On my Acid 8'10 115L - me: 93 kg, 6'3")
