My Nanospeed 800 got restrung with BG66 Ultimax @ 24lb and I noticed that it had a hairline crack. The problem is that I wasn't sure whether the crack was there before the restringing. I continued playing with the racket for a few more hours and the crack opened up. It's now basically unusable I was told by the stringer (who also owns the Badminton club I go to) that the crack was due to a clash, which seems legitimate because I remember clashing my racket LOADS of times during it's 2.5 year period. This racket was bought when I was still a beginner and progressed me up to intermediate level, so it is likely that the amount of clashes may have slowly worn it down. The purpose of this thread though, is that I want to know whether this crack was made by a clash or if it was a stringing flaw. I will appreciate quick responses because I want to make my mind up before Saturday as my shiny Nanospeed 9900 should be coming tomorrow If it was a stringing flaw, I'll check out another stringer. But if it wasn't, then I would prefer to give the NS9900 to the owner over the weekend to restring the BG66U so that it will be ready next session. Here are the pictures: Thanks in advance.
