Hi, I recently started playing the game seriously (getting coach once a week, hopefully playing more often with friends when I'm more free), and was thinking of going from the OS racquets I already have to a one properly customized for me. The racquets are my family's so the grip size isn't exactly right and I'm not happy with the balance. Also I tried my coach's 9x sq inch Prince racquet and preferred the feel, OS seems to wobble too much for me since it allows me to hit off center more often. Is a PD GT too advanced for me? My swing style tends to be moderate to short, and I'm a regular sized Asian (~5' 8") so my main concern is power..
