Professional training, one of my coaches who was in Poland's national team liked the racket. He never struggled with it.
I used it again yesterday for a singles game. Long story short, when you hit extremely - and I can't stress this enough - accurate, you have everything a player wants from a racket: power, accuracy and speed, but when you do not...
Numb. I tend to notice that when players with insufficient skill try to use the racket, their smashes lack steepness and end up coming in very flat (which actually works well against me funnily enough because I'm crap at body blocks with my left).
Yes, I'm having a love-hate relationship with this racket. There's times when everything's absolutely right and then there's times where I'd love to bang this little piece of sh*t on the floor...
Strangely enough , donno if its the BG80 force string , i felt the racket not stiff enough , tomorrow go change back BG 66 force , see how , BG80 force strung at 26 pounds still felt abit soft feel ......
Lol mate, there is no string such as Bg80 force, only normal Bg80 and Bg80 power. And I don't think string will affect your racket's stiffness, only control, placement, power, hitting feel etc.. Strange if you feel Bg80 is soft, or you can try to string higher to 27-28lbs, if still feeling soft with higher tension then you should find another decent stringer IMO. And Bg66 force definitely will not harder than Bg80 i can assure you..
Ahh that's clearer picture now, just get rid of that useless Bg80 power, it has nothing similar to normal Bg80, very slippery, tension retention is bad, try Bg80, its good.
On the left of the picture is a new Z-Speed, on the right is an old one. Both after a clash playing doubles. You can see the damage looks pretty much the same, so I would say the new version is not more durable than the old version.
