At the moment, I am borrowing my coaches k90s as he is stringing mine. They are both strung with this string -It is the cheapest of the cheap. -Durable -Makes your racket feel like a saucepan.... Although i seem to be hitting some of the most unbelieveable shots ever. There is NO feel whatsoever. There is NO spin whatsoever. There is NO power whatsoever. Is it the racket? Also...what do you guys think it's like.
