I think a lot of porpoising is due to inconsistent sail mast foot pressure - basically you let out your back hand in a gust which drops mast foot pressure and the board lifts - then you start fighting to control it. In these cases you need to lock in and just drive it harder (although can also result in some big catapults😀)
Perhaps before buying more stuff, you try a few things.
- Bringing the mast right back with the smaller sail might help to reduce this variation in mast foot pressure (it will be a little more squirrelly at take-off).
- Moving your foot straps forward
- try using additional shims that reduce the lift
- try using a sail size that you can only just get onto foil with pumping & in a gust (i.e underpowered sail )
