What a huge improvement over V2 Ultra! As a top 5 wing foil racer in the UK I was really excited to try Vx and ended up getting a whole quiver of them 3.5, 4.5 and 5.5 for my 82kg. The canopy is so tight that it keeps pushing you in almost no wind. Upwind angles are so much better than V2 and tacking is super easy to do. A lot of small but noticeable improvements like much better carbon handles with softer grip and S shaped strut makes things just easier. SUP style valve is easy to use. Even my wife who is learning loves these wing.
