To be honest, I don't expect the cloned versions of the rackets to be as good as the originals, the specs just aren't the same. But that's not to say APACS doesn't have its own great rackets. I'm sure if you compared Apacs with an equally-priced Yonex/Victor, the Apacs would be much better.
When we look at Apacs' own line like the Slayers, Lethals, and Tantrums (just to name a few) we can get a better idea of what they're capable of. And just as in every quality line, there are some good and some greats.
I just hope that no one is denouncing the entire Apacs brand after trying only the clone rackets. Try something like Slayer 88/99, Lethal 60/70/90, Tantrum 200/300/500. Even the Lurid series have been known to be good.
Yonex/Victor rackets are obviously not that much better than other brands, if you're just going by the cost. Why? Because a lot of that money does go into things like marketing, tournament sponsoring, player sponsoring, ads.
Just a few of my thoughts.
