Wouldn't you know it? The things you look for in a tennis racket—control and power—play against each other. The two were locked up at deuce until Andre Agassi helped develop Head's Flexpoint Radical OS. Dimples on this 10.4-ounce graphite frame at three and nine o'clock cause it to flex slightly, cupping the ball in the sweet spot for a fraction of a millisecond longer than rackets with less give. This micro-eternity lets you stay with the ball long enough to nail that dreamy line shot. But a wet noodle it's not: A superstrong metal alloy infused in the graphite cuts down on energy absorption, helping you smash your volleys. Just don't watch for the flex—that's indiscernible. Eye on the ball, people!
