I recently got I a new Prince O3 Blue racquet and as much as everyone loves stock form, it's time to get some new strings. I'm a 3.0 - 3.5 player, I typically like using a all court game in singles, but I play on a high school team so I do play more doubles. The racquet helps me with power, so I'm looking for a more controlled string with some bite and would prefer durability if possible. But, I have NO clue about strings, so maybe you here at TT can help me. Thanks.
