To all you great stringer out there, I was looking around YY US website earlier and found something interesting. 1) YY actually post their recommended stringing pattern on the web. 2) Take a look at the following link, NS9K has different (sort of) stringing pattern. http://www.yonexusa.com/badminton/badminton_strings.cfm#ns9000 Just a note for you all. Have a nice week!
