there is no powerfull racket its all depend on your wrist and arm speed movement racket just help u 15% max. to improve speed smash
15% is quite a good estimation, I think... thought the 'right' racket can "help" a lot. My current favorite makes me feel confident on every shot, and provides a good solid feel, and the fact it smashes like no other is nice, and actually the main reason for buying one...but eventually it's other characteristics are ftw... and I also a agree a racket doens't make the player (nor the other way around) but that a different discussion, and pretty much beating a dead horse...
these are some that can help u a little bit on smashing: armortec 700/800 off, ns9000x, also use bg-65ti / bg-80 string at least 24lbs hooooooooo..............
LOL kinda weird and i have a AT-700 but when i started i had a Cab 7000 DF and i got one badass smash.... the person hit it high up smashed it jump smash nailed him right on the cheek* when he left his cheek was all red i went to him said sorry felt badd LOL
u forgot to write down the string,since no matter how extra powerfull u n ur racket r,while the tension and the string is not suitable for it,then the output will be useless..so,my perfect combination is my kason carbon 3.0 with a nano95,at 28lbs..
