The question is better put as : are YOU good at smashing. How does it feel for you? That's all that is important.
bg66 is a powerful string that also has good control. a downside is its durability, which is quite low.
Yes your racquet is good for smashing. But are you good at smashing? Like if you give a new driver a Ferrari, can he/she drive it like it is supposed to be driven?
Yes indeed, the main question is that if YOU are good at smashing!! Not the racket! I believe most people buy at900p for smashing for if you are not good at this aspect, that will be no use
