I think the tornado will keep going for a while longer, and it will be going alittle faster as time goes by.
Mr. Roberts is correct that a smaller/potentially faster mast section could be made in carbon/epoxy. Don't know if they will do that though.
i think it is wrong to say carbon is 10x stiffer than alu. First of all carbonfibers are flexible and come on a roll while alu. comes in a billet. so carbon in it's raw form is actually soft and pliable. Carbon/epoxy masts built with the same shape as alu. bend to the same curve as alu. they can even be built to the same stiffness as alu. the differnce between the 2 is in the reflex characteristics, and the amount of bend. Alu. just keeps bending and it doesn't spring back as brightly as carbon/epoxy.
there are all kinds of ways to use carbon too. There is a kind of nylon resin that is used with it to get rid of the brittle effect. some bike handelbars use it. a bike made of the carbon/epoxy developes hidden cracks if the bike is dropped causing the bike to be essentialy unridable.
