Do dyed strings play differently from white ones? If the dyes can affect string life, maybe they also do some funny things to the strings' playability.
I think so. I feel white plays better in general, more responsive on Yonex strings. For Ashaway strings, I'm not sure. The MP in white has a different texture, different feel when compared to the orange and blue. The white actually "peels" like BG85. Orange and blue do not, go figure. Still testing...
