Costazzz, it depends a little bit on what fin you have. The best performance upwind/downwind on the HWR is when you get nose lifting as much as possible; you can do this with a really powerful lifting fin, or by running the mast track as far back as possible. I am normally running my track so far at the back the plate covers the serial number, then just moving it forward as the wind increases to have better control.
If you have a powerful fin already and with the track all the way back the board feels a little bit 'sluggish' (like it's getting stuck on the swells) then try the track halfway between the back and middle ;-)
