I always ask my stringers to do one-piece stringing method for me (only 2 knots on the frame) I doubt that the stringer pull the string too hard, because it's the machine which did the tensioning & pull the strings, the stringer adjust the string & the machine pull each string, every time one string was pulled, there will be a display of 30lbs on the machine's digital display. I always examine my racquet after each stringing process & found no cracks on the frame. Summore the racquet was strung nearly 2 months ago before it finally broke. After many hours of torture lol I can blame the stringer of course, but on which evidence?? I can't find stringing errors evidences that's strong enough to cause that serious damage on my racquet
I guess you should have asked your stringer to stick to the Yonex pattern I linked above It can also be done using the one piece stringing method, just that it takes a little bit of pre-weaving to get the pattern right before the tensioning.
good thing i don't like playing at high tension =) 25lbs works fine for me hope my 900t doesn't break like that... and erthk, i feel sorry for you did you get the racket replaced yet???
Nope, Yonex Sunrise Malaysia rejected my claim, they know I strung the racquet at a very high tension & caused the frame to crack
