The Orcas is for sure hard to un-feel??
I haven't been on anything else than F4, and they have never had a mast thicker than 13mm. So I have tried the Orca Vs other front wings, on the same mast.
Going from the F4 Hooki 760, 815 and 999, and Wahoos, the Orca was for sure a completely new feeling, with the same mast. The 685 felt like it almost had the same low end as the 999. But much faster, better glide, turned better, and actually easier to ride.
Now I am on the 75AX with my 87kg, +6mm wetsuit for the Norwegian winter.
Used to be on the 13mm 95.
Wing with upwind/downwind focus. And gradually getting into parawing.
