I could never find the right string and tension combination that suited me. I've never been picky with string and tension accept with this racquet. Really wanted to like it. Bought a set of 3 on **** and had them sent to vietnam. A friend here has one and I tried it out before purchasing and I loved it. Anybody get a sense that racquets play better when they're not yours? I'm trying out the iPrestige now and it feels very good. Had the iRad but felt very hollow. Awe, so sad, going through all the trouble of getting the n6.1s here.
