Hi, im kinda new to badminton and i wanna know how do you know if your sting tension is decreased? Also, is the loudness of the "pop" sound when you smash related to the sting type or sting tension? Thanks!
The tension decreases over time, you can't prevent that. Any experienced player will notice when the tension has dropped too much. Both the loudness and the sound itself are related to the string and tension.
don't bother too much about tension loss! for a beginner it doesn't matter too much, for advanced players, strings break too fast anyways. whether beginner or advanced player: i would always recommend to play a string until it breaks...
