Echoing Brittany's response, Andy also noticed the liveliness. He said, "Sonic Pro Edge had a crisp, lively feel, and the ball seemed to be jumping off the stringbed, but not to the point where I was losing control. It's on the softer side for a polyester based string, so that's going to give it a little extra juice. I would definitely consider it a livelier poly, similar to a Big Hitter Black 7 by Tourna or Luxilon's ALU Power."
