While Sonic Pro Edge is definitely a control string designed for big hitters, it is by no means a dead poly. In fact, Brittany found it to be pretty lively. She said, "When I first started hitting with this string it felt crisp and had a bit more power than I was expecting from a poly. I felt it to be a little livelier than the average poly but not as lively as a multi or multi/poly hybrid. I enjoyed hitting my groundstrokes with a little extra oomph behind them."
