While we can’t comment on the colors—the frames we receive are painted black so playtesters (in this case, all women) aren’t concerned with snazzy cosmetics—we can say that the racquet is light and higHLy maneuverable. And the comfort is phenomenal, with no vibration and a solid feel, thanks to shock-absorbing grommets in the head and silicon dioxide crystals that Wilson uses to fill the microscopic spaces between the woven graphite fibers; it’s done using a process dubbed nCode, which also increases stability in most cases. But if you hit off-center on a hard-hit ball, the W4, because it’s so light, twists in your hand. That’s reason enough for advanced players to steer clear. You’ll also notice that the W4 has an oval head instead of the standard round head. This increases the length of the main strings to give the string bed a trampoline effect, for power and spin.
This intermediate’s racquet is designed for women. Wilson calibrates the specs based on data it collected in focus groups: that female players want lighter, more powerful, and comfortable frames.
