I like the Lightning XX but would like more feel. I like the Babolat attraction power, but breaks in a month. I have used Wilson Sensation, it breaks after 2 months or so. I 've used NXTs. but haven't found the perfect string....I am hitting with the Yonex NSRQ 5. I hit hard, try for spin. Should I look for a crispy string---which one-----or a soft rebounding type of string...Anyone???Also---any RQ 5s out there? What do you use????
