I have checked in the information of your Yonex Armortec 700 shaft Serial:8146496; Cone Code:171289US (date=17 Dec 2008) to my information list of Yonex rackets made in Japan, its shaft serial and cone code are legitimate. However you still need to inspect the other physical features of the racket carefully and compare the specifications to ascertain its total legitimacy or authenticity yourself.

Yonex Racekt carries Cone Code for Year 2010 I am waiting new posting for Yonex racket with cone code for Year 2010. It will be interesting to see whether any change by Yonex to the cone code format of ddmmyxCC. I am also waiting to see Yonex racket with shaft serial beyond 9999999 to see whether any change to the 7-digit format of shaft serial.
If I stick my standard verification using the shaft serial and cone code, I would have concluded that your NS9900 was fake. This is based on the idea that the shaft serial run with the timeline based on the cone code. Hence, I held my tongue after I read all the post related to the isse. I have only 2 comment since you invited mine: Commet 1 Shaft serial are mostly lasered on for those Yonex rackets for newer models but the shaft serial of your NS9900 is not. comment 2 I believe Yonex ever made some mess up with the shaft serial corresponding to the cone code: Example: shaft serial of 6678583 to 6678587 with cone code of 230372JP (Date=23 Mar 2007) for 5 pieces of Armortec 900 Power (owned by Matt) which cannot fit in my spreadsheet. ie These 5 cannot fit in neatly between 1 piece of Armortec 900 Technique shaft serial 6677257 cone code of 070272JP (Date=07 Feb 2007) (also owned by Matt) and the next piece of Armortec 900 Power shaft serial 6679341 cone code of 070272SW (Date=07 Feb 2007) (owned by calvino)

Paint job is also good. Green cap at the bottom looks same as original. No PBSI , but yonex sticker is there.
No problem . I use the 'search this thread' feature and look for matching digits (within a reasonable range) verified earlier.
