Franck,

Quite clearly the f18 sail material is already heavily Limited.

No Aramids
No Carbon
No String
N0 3dl
No cuben
No 3di
No 2 plys
Nothing thats not on the already limited list.

You are clearly pushing the agenda of the big manufacturers. Please stop it. Its getting very old.

F18 is and has always been a development class. That is a fact.
