Last Thursday I played with my AT70 again and noticed the following crack: (Click for HUUUGE) The crack is only visible on the inside of the racket but I figure it wont take long until she dies. The only weird thing is: I lost a Nanospeed (cant remember the Nr) to the exact same problem. A crack starting from the inside on that exact spot. Both rackets still have the standard Yonex stringing it comes with. A few years ago I had to restring regularly, nowadays I just break the whole racket . I hope my Voltric 5 can stay with me for a longer period.
