BABOLAT AeroPro Drive GT Tennis Racquet
The Babolat AeroPro Drive GT is famous for being the racket of Rafael Nadal's as well as Fernando Verdasco. But if you want to think about POWER, think about Sam Groth. Avid tennis fans know about Groth, but if you don't, he's an Australian player who routinely hit serves over 140 MPH at the 2014 US Open against Roger Federer. He was clocked over 160 MPH in a Challenger event, so that's unofficially the fastest serve in pro tennis history.
If a racket is yielding that kind of performance, we have to pay it some attention, especially when it’s generating the sort of spin/control Nadal demonstrates. The strung weight is 11.3 ounces, a little on the heavier side but if you want to go heavier you can add some lead weight. The racket performs with string tension as low as 55, but feel free to go lower if you are using a poly string. If you want power, try a Luxilon or similar string and drop the tension further.
