I don't believe there is an absolute rule on this. According to lab testing done for the USRSA about 40% of 17g strings are stiffer than their 16g equivelants. The rest are softer. I believe it was a piece in Tennis Magazine that made the claim that thick string at low tension was best for generating spin, not USRSA.
