I bought Helium for wingfoil use and I love it it worked well in it. I’m a beginner on the wing, but I’ve windfilled for a few years, so there is experience from other wings as well. The wing flies at a really low speed and glides lightly. The fuse and stabilizer are quite small, so the foil reacts quickly to pressure changes. Today was a typical light "sea breeze" and I really enjoyed driving with the 5.0 wing and Helium a lot.
The bag / box in which this is delivered is indeed quite gigantic, but then does not break down very easily during transport.
The method of attaching the mast to the board is very comfortable in use. Anyway, the parts screw together to form a streamlined and neat whole. The front wing could sit tighter on the body piece, but when tightened with three screws, it does feel that it stays firmly in place. The included torx key is perhaps mostly of “sufficient” quality, so you might want to get a better one from the store.
I think the value for money is very good. The Kujira 1440 front wing alone costs € 800 and this package totaled € 899. There are also cheaper packages, but I think the price is well below the median and the functionality of the package is quite top notch. For example, my old Slingshot looks like a pretty amateur pile next to this foil.
