I hope you guys can contribute such review about your favourite strings and their speciality]
Yonex BG80 strung at 21lbs on Wilson Titanium 5.0 (medium flexible racket) and Yonex BG70PRO strung at 23lbs on Gosen Grapower 950Ti (very flexible racket). Tried Yonex BG65 and it lost tension too quick in my opinion and has a very dull sound at impact. Tare Panda
