I want to start my Supfoil career now too.
I already have a custom board 7'11 x 30,5" tomostyle , 129 l, with two 25cm US-rails, starting 40cm, or 16" from the tail.

Europe located and not able to use a GoFoil (no Tuttle), I have access to the following foils, which would you recommend?
Mainstream, well known:
Slingshot Surf H2 or H4
Naish (???)
Takuma (new V400 ?)
others?

Exotics UX-wise:
MFC SUPfoil (to come)
AFS SUPfoil
Fanatic (not rec. by their own teamrider ;-)

Exoctics pricewise, their price makes them attractive:
Okarbon
Gong
Chinese copys
others

Thanx, Alex.
