Interesting and surprising. What outhaul exactly do you use?
This was yesterday with medium downhaul (for once) and low wind outhaul (meaning red rope). We had 15-25 knots. The sail was lighter but honestly could have gotten away with a Min 1 setting (the one tighter than the lowest one) just so I have a little more support in the lulls. At the end of the session I released 1-2cm outhaul and it was perfect, pulled pretty hard.
The previous days we had gusts up to 28 knots and despite the Min1 setting, it was fine (just a little heavy in the gusts). But I sail side-on so on the wave, the sail loses quite a bit of power and in the jumps it's never much of a problem as the waves are sheltered there too.
