Thanks. I'm considering buying either this or the Yonex RDX 500 MP. Both at about the same price. Prince is cheaper and maybe the paintjob is in better conditions, but it would need new strings and a bigger grip size (nothing too difficult) so the price would be about the same... Could you compare them to the NBlade MP (my spare racquet wich I would replace and give to a friend)?
In the end, the only thing a new racquet will do for you is make you suck in a different way.
