Thanks for the tip. Those lines are 30inch as recommended by Matt Pritchard at his clinic recently. He did say though to have a forearms length for harness lines, which 30 inch still isnt enough.
I've just purchased a new 'Surf mount' that sits on the front of the board.
I figure once i've captured a bunch of videos from various angles I can clip them together to produce a fairly reasonable video.
I liked the Contour HD because of its ability to sit properly on the side of helmets (not on top), as i'm also capturing some mountain biking footage.
The new Contour HD will have the ability to stream bluetooth video to your iphone for set up ability. mmm wonder how much that will be
