The majority of people seem to think that players use very low powered racquets with "lots of control" but when I analyzed some setups I realized most aren't so low powered. Take Federer for example - he strings at about 22 kg with gut/poly. This powerful string setup is balanced out by a low swingweight and small headsize. Sampras - very high tension but all gut and a very heavy racquet/SW. Then what about people like Djokovic and Soderling with near-380 swingweights and medium tensions? These seem like powerful setups. Not to mention the Babolat guys - they are definitely power-oriented. So the question arises - how do they control such powerful setups?
