Well... Nanoray z force 2 doesn't exist. Haha
I assume you're talking about the voltric z force 2, and you're right with your assumption. Lots of people buy them, then realize that they can't handle the weight or stiffness and try to sell them.
Strong player, with good technique can use ZF2 4U.
Very strong player, with excellent technique can use ZF 3U.
The playing style does not always match with racket types. It depends at which level you play, how good is your technique, short or long swing, how good is your defence, how fast can you swing, what you prefer etc.
This rule: Offensive Player -> HH, Defensive Player -> HL is IMO rubbish. Every rally has defensive, neutral and offensive moments. You can't play everytime the same against different opponents.
Haha yes you are right, I meant voltric z force 2. Thanks for your input
What sort of players should zf2? What sort of playstyle?
My experience with the ZF2 was that it was "slow". It took a bigger swing than other rackets; it was harder to make shots with just finger power or clear with just the forearm. That said, using a full swing it was super easy to clear end to end. I could lazily clear end to end with very little effort. If I had time to set up I could smash very hard with this racket. It was very precise on drop shots and net shots.
I think if you are the type of player who likes to play a long strategic rally (and maybe end it with one booming smash) this is a good racket. If you get in to lots of fast driving rallies or you smash 5 times in a row (or return 5 smashes in a row) this racket will be more tiring and/or slower than other rackets. LCW is the first kind of player and I'm not surprised he uses this racket. I am more the 2nd kind of player (and not nearly as talented) so I have given up the ZF2.
As a VTZF2 3U user I first found the racquet a faint bit heavier in the head..But after using it for a couple of games I found it a breeze to use..The shuttle goes where you intend for it, but a mid hit and its unforgiving..But fun to use all round and the sound is boom boom shake the court..
