The Wilson Pro Staff Rok 93 features a 18 x 20 string pattern. The pattern is very dense in the centre of the racquet, making for a small sweetspot that affords the user lots of control. The Rok 93 is generally termed as a control orientated racquet for this reason.
There are two different Rok 93 versions. The first released has 'Hyper Carbon Double Braided' written on the side while the second version released has wilson in silver on the throat are. The first version is 10g heavier. As a control racquet, users are advised to string at a lower tension than they may do for other racquets.
