kiteflyer 87, the harness mount is very comfortable I wore it for about 2 hours, i did find it a bit combersome after about an hour, but I was having far too much fun to come in and take it off.
I'd say its fine for an hour or so, but any longer and you'll probably feel like you'll want to take it off.
kiteonsnow - My camera is the gopro Hero 2 and I used it on the default settings, the waves were bigger than the camera gave it credit for, but I'm wondering if I changed to a less fish eye view then the waves would look bigger, but then you might not get the whole shot in. I'll have to have a play with it, when the rain stops
