How hard is it just to give new string? I give NEW STRING away at times. Example: at yoyo class a girl was walking around picking up players used string. She ask for one on my yoyo. What I did was Pull out my bundle of string and GAVE her 10 green polys. She thanked me and ask how much? I told just take it, it fine. So what I’m saying is just give 2 or 3 strings away, it won’t hurt you and the player will appreciate that.
