Nice design work Gunnar. Good to see some independent ideas on wingboards. I have come to the same conclusions as you after a year on the wing and just built my latest board incorporating some of the same ideas: front foot volume, no tail chine but just a little tail rocker. I kept the side chine to the tail as I notice that when I am in swells and banked over that he tail sometimes touches the water on the turn. I dont know why people persist with the tail kick. For SUP foiling it makes sense but for Wing Foiling no sense. What volume board are you riding in the video and what are your conclusions after a year about board volumes for real world conditions?
