Hi everyone, I have - Wilson ncode nzone Force (written max string tension 26lbs) - Ashaway VR Electro (strung at 24 lbs) - Ashaway Nano Superlight (strung at 24 lbs) and I'm using Yonex BG66 string... Has anyone any experience about their unofficial max string tension? Bcoz I strung my Wilson at 26 lbs and after around 1 week (4x play) it seemed loosen. Should I strung it higher 1 - 2 lbs? So when it drops it will be around 26 lbs? Thanks!
