I got my racket strung with VS gut and hurricane pro and after about a month of play i began to notice that the hurricane had little ridges or indentions where the VS gut sat and that the string no longer moves when hitting the ball. As i understand, you need some sort of movement on the strings to generate spin and since this has occured I am finding it tremendously difficult to spin the ball in. My play style involves alot of spin and now I cannot seem to place the ball in the court. I switched back to another stick with a different sting set that I didnt like and found myself hitting more in with that than with the other stick with the indented strings. I LOVED the strings when I first got them yet now they are...bad.... Is this normal and how can I prevent it. String tension is 58. P.S. What I mean by indentions is that the strings set in those ridges and do not move. They literally hold themselves in place in the ridges.
