Hopefully tomorrow as wind is coming. It might not make a big difference because I set the mast 3/4 forward already. Some time ago I tried to oversize my old Tiga 270 (x53 cm) and it was not very fun, though the mast track is waaay forward compared to modern boards. What made me think mast track tuning is not so critical is the fact that one single position can accomodate so many sails. But your trials suggest something else: the sensitive zone where the behaviour varies a lot may be located much further back. Will try this setting as well and the mystery may be over.
