Kev, i use go pros on #2007 , i like the backward facing view from just behind the bridlewire, as Liam has often posted footage off as well.
make sure you always tie them on as one bad wave could either knock the camera off or something happens to hit it off. the view gives a good clear indication of what the sail is doing and a nice view behind, sticky pads mounts are ok. make sure you dont have too many fittings so that the camera can be adjusted asa bad wave can easily knock the cam to the deck.
ive tried the tiller bar view and not a lover of it unless you like watching yourself , and it moves around every time you push the tiller bar.
easiily mounted with a handlebar bracket and adjustable connector.
as for the mast mount like Liam uses i havent tried that yet.
i have got one mounted under the front beam on the hull but not used it yet i think the waves would soon hit it out of adjustment.
never buy the real go pro kit as its so expensive and you can get it cheaper on ebay in large kit forms.
if you have any stuff to post on youtube post the link, mines there under Kevin Sandover
