This looks like an interesting technique but apparently it takes a bit to time for setup and you hair to wait for the right condition (strong gust) to go.
One alternative I have seen that is way faster and probably easier is simply to sit on your board, hold your wing over your head with one hand and do a pop up using your free hand, and off you go (see video from 3:50). Pretty much like a sinker start but with instant go. Anyone tried it? I will be giving a try very soon.
