Scarecrow,
I'll try checking with some of the other guys to see if they know the numbers on the current masts. As the superwings are extruded by AHPC, it is possible that they have not run the numbers on it but gone by experience when doing the die.
Female mould and laying up a 'classic' carbon mast is a possibility. Doing it in wood would be a more fun project on the other hand. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> But I am always willing to listen common sense.. Anyway, it is not for this year. We are using old Tornado masts for now.
