Hello, I would appreciate some help choosing right racket for me. Background: 26 years, 186cm, 75kg, (taller/thin), playing 5 years. Level intermediate, racket Head Metalix 10000 (2009, top in class, technical, medium shaft, head light (in hand)). I think its time to get a better racket with newer technologies. Im playing 1-2 week, my style is that i bet more for technical shots around the court then just smash after smash and pure aggressiveness. I think my racket is good for pure technical style, but doesnt give me enough durability for atleast intermediate smashes and pressure oponent with strenght. My weakness is, if someone keeps pushing me back on court, sooner or later i wont have enough power to hit his back court as well and he smashes me from center of the court. So i think if i get little more agressive racket (stiffer maybe?) i wont lack of power from back of court and still be able to play technical shots, becouse i do smashes just when i create an oppurtunity to have perfect chance, becouse opponent is in trouble.So racket for technical play but with decent agressive smashing power i guess. Budget is around 100-160$ and i prefer Yonnex. I found voltric 9 or 70 could be more suitable for me, but im not sure if i would feel good about head-heavy racket. Nanospeed9900 looks like good all around racket and Nanoray 800 seems nice too. I know its best to try to play with racket, but i ll have oppurtunity try them just in shop, so i try your reccomendations. Thank you for any opinion.
