As far as I know, Maria's Head racket is indeed heavier but is more flexible, so it eases the shoulder unlike Prince rackets which are known to be very stiff.
I do not think so, just look at the racquet she used when she first decided to use Head and the one she's actually using, big difference, not the same racquet at all. And at the beginning of 2011 she was using a Radical MP but not anymore.
