I have strung the same racquet twice. First time weaving one cross string at each time and tensioning it right after weaving the string. Second time used the "one-ahead" technique while weaving the cross strings. First stringjob: 37 DT Second Stringjob: 40 DT The racquet is a Pure Storm 16X20 strung at 57 pounds,constant pull machine. The string used is Babolat Pro Hurricane Tour 1.25 mm What are your thoughts regarding this difference in DTs? Thanks!
