The most important part of the testing (in my opinion) would be to make sure that the testers are actually people who are very well acquainted with foils. People who understand them and are experienced with them. And not people who have an interest in proving their inferiority.
On the contrary, I would like to see some relatively new foil flyers try them next to their LEI counterparts. I would like to see this crew of testers take the time to learn the few little things they should know, and then provide more of the same honest and open minded opinions. I have to believe none of them would have an interest in proving anything either way for any of the tested kites.
As for OceanAdventures expensive comment...
More expensive for sure, and of course buying just to test for the rest of us is unreasonable...
