The i20 mast shape could be improved as well, a pear shape is fatter than a true wing shape, so it you make a mast in a wing shape its going to have less surface area and less material, (alum or carbon) so it will be lighter in that regard. Its also going to be stiffer by nature, more material in the fore/aft axis.
If the i20 class does go to Forte, they should demand a true wing mast shape, dont go with the T section he's using now.

I'm a fan of the Forte stuff, its durable and less expensive. A $1000 wing mast secion would be awesome, think about a second mast for you Acat to go out in a blow, or to use when its windy, make it stffer. Anyway a Forte wing mast would be a good thing.
