I just demo'd the ProKennex Ionic Ki 5 315, and wow, what a comfy racquet! I've been playing with a Pure Drive 2012 the last couple of months, but suffering tennis elbow problems because of the frame stiffness. The Ki 5 315 is almost a perfect replacement, but I find it lacks the power and pop of the PD 2012. However, the Ki 5 315 demo shipped with a crappy set of strings and I have no idea what tension, so perhaps that's part of the problem? I'm wondering... if I add some lead tape and use low string tension on the Ki 5 315, would that give me the power I desire? I've never used lead tape before... do I add it the 3 and 9 positions?
