Hello I'm the owner of a Wilson KSix-One Tour 90 and i've never had it re-strung before. I'm still using it with the strings that came with it (Wilson Sensation @ 55 pounds). I've been using it once every week for two hours the last few months, and I know it's just a matter of time before one of the stirngs snatch. So - I really need some advice as for what I should restring it with, if that's even possible. I'm still very much a beginner, but i'm very happy about playing with the racket, and my only problem with it is that I feel that the strings have lost (maybe they've always been like this) too much tension. I'm interested in a setting which will allow me to practice a lot with the racket without the strings snatching easily. Thanks!
