Hi. I'm wondering, do you change your strings before a tournament. You see, I'm using Yonex Ti-10 with BG68Ti, strung at 22 lbs (strung 4 months ago). Over the past 4 months, I normally play only once a week, about 2 hours every session. I haven't see any wear and tear on my strings, but the fear of the string snapping during my tournament is always on my head. I do have another spare racquet (Yonex Ti-8), but this racquet is still my favourite. But, I normally don't like to use racquets which are just strung. I normally need time to get used to it, like playing with it for about a few times. This might be due to the fact that I want the string tension to drop a little bit. Now, the tournament is 3 weeks away. What would you do if you are in my situation? Replace the string (and use 3 weeks to get used to it), or not replace it (the last time I use this string, it lasted 10 months, with the same intensity - play once every week, 2 hours each time). Thanks for your opinion.
