Hey guys, I'm new around here I've been playing tennis for about 7 years or so and I'm 14, I'm really looking forward to learning from you guys. Anyway at training tonight I broke the big bangers on my Pure Drive, it is two generations old, restringing with the big bangers would be around $60. My coach has a brand spanking new Pure Drive GT for sale for $180, I'm not sure what to do. Is there a big difference between the new and the old one? Thanks for your help.
