BG65TI is now my new favorite string. I got it strung at 24lbs on my nanoray20, first hit it felt like playing with a cricket bat. But after a few hard smashes the string magically adjusted to my offensive playing style(string got softer in the sweetpoint).I got it pre-stretched there for barely felt like it lost any tension even after an hour of hardcore non-stop play.Now down to defence mode, the string has stupidly high amount of power rebounding a smash, and slices are a little slippery but getting used to it. the Repulsion is perfect for me since i'm a hard hitter, clears and smash didn't need that much effort to clear and smash with good power. Control is alright instead of explaining i'll rate it 3.5/5. thanks for viewing
