Racquet: Wilson Pro Staff 97 v14 ($279)

Back to its roots. That’s what Wilson set out to accomplish with this latest update to the acclaimed franchise. Their engineers wanted to rediscover more of the feel found in earlier versions of the frame, and combine it with the forgiveness and playability of the more modern models. This is primarily achieved by altering the bending profile of the racquet to more closely resemble those past iconic frames. The trademark Pro Staff feel and precision are amplified without losing its modern flourishes. Experienced ball-strikers will appreciate the racquet’s respectable power and command to spare. At home on the baseline or net, the frame’s versatility has been a hallmark of its enduring popularity.
