Spin is in with the new super open string patterns by Wilson

With the release of the new Wilson Spin Effect racquets, the Steam 99 S and Steam 105 S, people are talking about the way that spin is produced and what effects a racquet can have on spin production. Wilson utilizes an open 16×15 string pattern that it claims helps to produce noticeably more spin than a traditional 16×18 or 18×20 string pattern. The difference lies in there being fewer cross strings than main strings, thus opening up the stringbed and creating more space in between the strings.

Interestingly enough, our TW University professor, Crawford Lindsey, was onto something very similar a few years ago when he started testing the effects that different string patterns had on spin. He conducted experiments (outlined in his “Spin and String Pattern” article in September of 2010) to test which string patterns were more effective in producing more spin.
