Hi,
Sorry if this has already been discussed but I couldn't find any related topic.
I saw this wing on Duotone website (www.duotonesports.com/foilwing/news/detailed/behind-the-design-of-the-foil-range/) and it says "Unit" (in the middle of the wing) but it has only 2 long handles and no other information anywhere else.

I also saw this wing on on the video from 2021 GWA Wingfoil World Cup in Morocco on 14:05?t=845

Does anyone know if it was just a pre-production version of the Unit or it's a prototype for a new 2022 version? (which doesn't make sense as why would they call it "Unit" again?)

I just found out it's the 2022 Unit D/Lab with the Aluula (light and very expensive) leading edge and strut.
