Hi all, I have been using cheap 15G nylon strings on my RD-7 strung at 78 main and 80 cross for a long time. I am a 4.0 rated player that hit with two-handed on both sides and have a aggressive baseline game. Best strokes are probably my groundstrokes and return. Worst strokes are my volley and serve. After reading posts on this forum for a while I would like to try some different strings that will help me to improve my game. I really like the tight feeling of the strings but would like to try something with a little more feel compare to the nylon I am using now and hopefully something that holds the tension a bit longer. Any suggestions? Basic syn or any hybrid?
