Which raquet is better? I am planning to buy. Armotec 900? Arcsaber z slash or nano9900?
All of this rackets are extremely good since their are the high end product in each of their classes. Since all of them are good rackets, the only issue now is whether any of this racket specifications suits and blend nicely with all the requirements that you have as a player.
You must understand that for Yonex racket, the class that the product comes from represent certain head balance criteria:
Armortec = Mostly head heavy balance racket
Arcsaber = Mostly head balance (even) racket
Nanospeed = Mostly Head light racket
If the quality of all your hits are satisfactory after using a nanospeed class racket then theoretically, if you change and use a armortec type of racket, its unlikely that same quality of hits can be produce since its from a different class of racket. Therefore, you can only judge those quality after trying all of this and if one of it suits you well then, that racket will be the choice of racket for you that eventually will be the better racket as to compare to the other product.
