I'm looking for a durable string that also has above average playability. originally, i liked the play of stamina alot, but due to my playing style, it broke quite often.(like every 2 weeks) Now, I use Babolat Pro Hurricane, which lasts a while, but I really can't stand the playability...um. I'm a highschool player, who hits with heavy topspin. Anybody know a string that is durable yet playable at a decent price?
