As I'm lighter I stick it a bit backward but not much. I have been using sails from 3.7 to 7.8 on different boards with consistent footstraps/mast base position. Some older boards have mast track way forward, so I have to make compromise with the spacing, but then I can switch sail or board without changing any setting (excepted harness lines). Changing fin seems to have much more influence on planning/speed/control.
