The Story.... I played again last night with a new setup, FXP 17 Mains @ 57 lbs and Solinco Tour Bite 17 Crosses @ 54lbs with one of my relatively new racquets (see signature). I am a relatively heavy topspin player from the baseline but I generally have an attack game. Anyways, I played last night and then POP! 2 strings break at the same time! I was puzzled by this. Both strings that broke were mains, one in the center (where you would start your mains, then skip one main, and then another broken string). The break was in the dead center of each string and in the center of the frame (so it was a square hit, not a mishit). What kinda makes me mad is that the string only lasted about 6 hours and Tour Bite isn't cheap :evil:. The strings didn't begin to notch yet before it broke. The Questions.... When strings double break like this, does it relate to my string job (I personally string on my own). Did I possibly string the FXP too high as it relates to a thinner gauge? I regularly string around 54/55 lbs. with FXP mains. I strung this setup around 57 lbs. Could it have been the FXP string? I bought 10 packs of FXP in bulk around early June this year and have gotten through 6 packs using half sets each time I string. So I guess I string rather frequently. Are the strings considered old or do they have a long shelf life? Am I not storing the strings properly? I have a roll out off brand craftsman-type work bench and store the strings inside a drawer. I didn't notice any kinks in the string and I am usually very gentle when stringing. Should I look to buying a thicker gauge multi now? OR am I totally over-analyzing the situation and just say I broke two strings at the same time, which is pretty awesome. I know it is a lot of questions, but I have had this happen to me twice now with the FXP. The first time it happened around 12-15 hours, which I thought was normal. This time it took half the amount of time, which worries my stringing abilities. Thanks!
