I have two sets of this string and I hear it's excellent. A friend of mine just gave me them for free. He said it's a great string but that he's sticking with Babolat Gut from here on out. Question is: Does this string play best as a full set-up? If so, does it play okay at lesser tension? I have a Youtek Prestige MP and I'm currently using Bi-phase 17. Could I hybrid Cyber Blue with the Bi-phase? If so, should the CB go in mains and bi-phase in crosses? Any feedback would be appreciated. I want to at least try these strings ( I always enjoy anything "free" ) ***I meant simply Cyber Blue, not Cyber Flash Blue. What is the difference between the two?
