YOYO string

i have used yoyo factory string for a while now and i want to try a new string just to get the feel for what is out there. I have looked at candy wire string and wanted to get your opinion on it? what is it made of how does it play? is its price cheap in comparison? IS the fat string better that the skinny string, or should i get type e, type s? What is the difference some one please help me what about kitty string?
OR what are some other yoyo strings you guys recommend? (cheep ish and 100% polyester preferred.
