Here's my story:
Two days ago,i just lost my 800de to the stringing machine,to be exact,the string.My string,which is the mmoa nano power 66,broke in the middle of stringing process.It was set on 26,27.Then suddenly it broke,and the unbalanced tension around the racket force my racket to change its shape,and then..over.
Yesterday,my at300,strung with BG66 26,27.Just strung for a day,played only once.Then,i took out my rackets and put it on the sofa.Well,it's a habit,u know?Hehe..then,i go into my room n go online.Suddenly i hear broken string sound outside.Then i check out n found out that my at300 string is broken.Luckily,i found it out soon enough.AT300 survived.
Few months back,i also lost my arc10 to NBG98.I found that it's broken when i was opening the bag the next day after i played it a day before that. Never really used it though.I always pay attention to my rackets everyday,include its string.Not like it was worn n stuff.It was strung at 28,27lbs.
About two years ago,I also lost my TSF300A to a BG66.Happend in the middle of the stringing process,just like my 800de.Was strung at 27,28lbs.
It all happend in a great weather,which is not happend because of an extreme condition or so.
Is it just me,or someone else here also ever experienced the string broke by itself,even though it's not even worn out,since u haven't even really use it.Most likely not more than 3 times of playing.Or in the middle of the stringing process?Is it the 0.66 curse?or was it because the string is from the stock that's not properly sealed or old stocks?
