At the beginning of summer, my strings were only breaking once a week. But it has slowly started to break faster and faster, i play approx 5 hours a day and I have improved a lot since the beginning (esp my forehand has way more spin and power) but I don't think i am good enough to be breaking strings anywhere near this fast. My strings are breaking on the 4th or 5th cross around there everytime, so in the upper center of the racket. I use a youtek radical pro. I am stringing it right becuase even when I bought my next one i had tenniswarehouse string it and the luxilon alu power broke in one day only ( 3 hours). Yesterday, i had strung it with klip pro line 2 17 and it broke within 2 hours. Today, I strung it with luxilon big banger original 16 and this string seems to be pretty durable which is good because I have played for 3 and a half hours on it and it still hasnt broken, although there is severe notching so it will break very soon now. I don't know what to do because I can't really afford to keep buying strings and stringing everyday. I string my own rackets by the way. I don't even get how the pros aren't breaking strings every half hour the way they hit the ball. I am pretty sure I am stringing it right but will take a video tonight or tomorrow just in case. Any suggestions? Thanks.
