I'm looking to get a new string job done and a string I can rely on for a while. I recently was using Gosen OG Micro 17 strung at 61 Lbs with my K90 but it lost tension fast. It was good while it lasted though. I just don't like the whole trampoline effect of less tension at all. Could you please recommend a string, Preferably Syn Gut/Poly that I could use, That is durable and works well at high tensions. Please post a link to the site to buy it at, Also what tension would work best. I mainly play a Serve and Volley style game with occasional change to baseline. I wanted to try out Topspin Cyber Whirl, But I didn't see many reviews on it, So would that be good?
