Apologies if this is a thread form before. I tried searching but couldn't find a thread that talked about it. I have a Arcsaber ZS and I got it strung to 24lbs 6 months ago with BG65 Ti. I am wondering how to know if the string tension is at a point where it needs restringing? The strings are not broken, the racket plays fine. Do people restring even if the strings are not broken? Is there an easy way to measure string tension (without buying specialized equipment)? Just wanted to know what people do.
