So far I was looking at Slingshot Outwit, Naish Hover Wing/SuP and Fanatic Sky Wing. I don't have the possibility to test them. That's why I'm phishing for reviews. Trying to catch what people say about their stability and all-in-all behavior. The same reason behind my question re board volume.
I started on the Sky Wing 5'4 (95L) and for my weight ( 80 kg) found it quite stable. However, I didn't like the concave deck and the large gap between the front and rear straps. Also the foil tracks are relatively far back from the foot straps favouring foils with the wing in a more forward windfoil type position (e.g. the Fanatic foils).
Have since moved to the Takoon 4'10 85 L. It's lighter, cheaper, allows me to setup my preferred foot strap stance and the balance at close to standstill doesn't require me to step forward out of the rear strap like the Sky Wing. The 85L volume is fine for my weight even when the wind drops right off.
Whatever you buy make sure it has a handle on the bottom of the hull. It makes it so much easier to carry the wing and board.
