Nice Video, my harness is the dedicated Dakine, with the flat hook, that can lay flat and when not required slides to the lft to it´s own pocket. Also It has a nice rear line for clipping the board leash as well. I went with the windsurf harness lines but too think for the job, GONG ones are perfect and the top tip is to just grab your boom handle and hook your thumb on the line to stop it flapping around.

which harness hock is that? The belt from gong?
