Maybe that's just what Kalki wanted- to have VD as the hero, because he corresponds very well as to what a hero must be- brave, resourceful, funny, romantic(?!), sometimes idiotic- in short, a perfect blend. And his life is not too well recorded either.
AV, on the other hand, is a great historical character- someone whose life is too well documented to be fooled with. If someone argues that AV did such-and-such a thing in a certain year, there'll be too many arguments. VD's life on the other hand, isn't too complicated.:-)
And there's the fact that VD married the great, unattainable princess Kundhavai:-) Talk about a rags-to-riches story!
