There's this popular myth out there that the better player you are, the more under-powered racket you'll play with. This is of course very far from the truth. In fact they play with very powerful rackets but they know how to control all that power. Now in the case of the pros, most of this power comes from the racket's swingweight, as opposed to a stiff, oversize tweener that most people would refer to as a power frame. The higher swingweight allows them to have power and stability when having to defend, as well as power and spin when attacking. Of course the higher the racket's power, the smaller the margin for error in its application. That ability to control power is what separates the contenders from the pretenders So my suggestion to players who want to be the best they can be, is not to get caught up in the "control" craze, certainly not at the cost of your arm health. Have a comfortable setup that provides good stability, spin and power on tap when needed. Practice to tame that power.
