Hey guys, I was going to buy a racket between these two, not sure which one. Some info about me: I've been playing badminton for 6-7 years. I'm playing on my college team right now. My first decent racket was the Victor Super Nano 3. I'm 6'4. I play both singles and doubles, but I'm going to start playing doubles a lot more on the team. OR Also, if I do end of getting the Voltric Z Force, I will most likely be getting the 4U, aka lighter version. Thanks for the help!
