Hi. I play using a Ti10 and BG68Ti strings at 22lbs. I don't play that often, I normally just play once a week for 2 hours. Because of that, my string normally lasts for at least 6 months. Recently, I broke my string and restringed it. Wow, the new string just feels so powerful. The sound is so nice and it's really repulsive. Now, the question: for a user like me whose string only breaks after such a long time, do you cut the string before it breaks? And when's the best time to cut the string? There is a doubt on me when to cut the string: How am I that sure that I start to lose power because of the string, not because it's one of my bad days in badminton? I don't mind to cut the string eventhough the string might be expensive. I'm willing to sacrifice a little bit to get the best out of badminton. And, do pros cut their string frequently??? Or do they restring only after their strings break?
