Not really the windrange in which I'm using a foil, but after my speeds on the 8.2 and M wing I wanted to give it a shot for the Belgian record. Just did 9 runs and changed to the JP71 as the wind was going to increase. Work to do Vincent ;-)
Happy with the speeds, both feet in the straps, but I think I won't be much slower in 15-18 knots (with this combo).
