Profile for large DIY wing

I’m just wondering if anyone has played around with making one of these super large wings (like Fone Gravity 2200, Gong XXL, etc.). My previous wing build was a 633 inspired design that I believe someone from here put on Thingiverse. It has been working great under various power sources. 3D printed core/carbon skins. But I didn’t design it or find the profile (h105 in that case). So I’m curious what kind of profiles people would recommend or have been using for giant wings like this.

I also have a combo efoil and light wind kitefoil agenda at play here :wink:
