Tennis racket recommendations?

I'm a 5.0 and I think I need a new racket. My brother and I play with the babolat aeropro cortex. I am not sure if I should change away because I kind of like it because I play with topspin. The problem with it is that I sometimes want to play flat and the aeropro is not great at hitting flat. My brother is as good as I am, maybe better because he plays all flat. He definitely needs to get away from babolat. Note that rackets must be head light and must NOT be very stiff.
