Hello, I spend some time on buying a new racket and i bought the YY Ti SwingPower SS. Now I would like to spend some time in the world of strings. I have to decide which type of string i want in my new racket. Normally i don't care (my coach always puts something in it, i think it is a Toalson string). I am not a powerplayer (not very powerfull smashes), i have pretty sharp drops and good clears. Can you advise me a string and at what weight? Thanks!
