Hi, I would like to seek some recommendation in regards to my string. Currently using BG-80P at 23lbs, and frequently I find my shots having too much power which results in having it to fly out of court. And when net play I find myself returning net shots that are too high, wondering is it something gotta do with my string tension.. I'm currently thinking of changing my string to yonex nanogy 99. Should I keep it at the same tension or should I increase it since I got much strength, or should I continue with BG-80P but to increase the tension of it?
