For the F20c, there is a definite "twist" to the boards. It's not a straight curve...
Not all curved foils were born equal.
Symetrical section curved foils with different angles of incidence along their span on the F20C, compared to asymetrical section curved foils with fixed angle of incidence along their span on the french maxitris.
It will take a while to fine tune curved foils in cats. And never forget the "S" foils that were barely tested.
