Can you describe the difference between the vis and FZDALC?
Of course I can.
FZD is definitely softer than Vis. Without a doubt it's easier to spin with FZD than vis let alone TBALC. I'm saying all this from the point of view of an average player, which includes me. Of course, technically advanced players can spin appropriately with any racket. Furthermore, the shape of the handle is certainly different and there is no dilemma for me - I like the handle on the FZD much more. Smash is easier with the Vis. FZD is really unique blade.
I would also add that there really is no best rubber for a particular racket. Of course, there are combinations or racket types that I wouldn't recommend with certain rubbers, but that's another story. And let me make a small digression, while I was in tennis for a couple of decades, I must have tried 50 rackets and as many different strings. Call it EJ or not, I've identified exactly what works for me and what doesn't, what stiffness, mass, balance, head size, string type and tension.
I have a similar approach here, I've found what works for me and what doesn't. And I enjoyed every second of that process. The racket must be balanced towards the shaft, standard size 150x157 no bigger, FL handle, off - to off, carbon layer, good feeling, no koto, limba is ok, and I like hinoki. Of course, it is not that simple, it also depends on the construction, specific implementation, etc. But generally these are my preferences.
Back to the topic and OP, Rosena is a really good rubber. I understand how you have the impression that it is kind of slow or dead on contact. I would rather say controlled, without the trampoline and catapult effect. But I would say it's good for you (as well as me).
I suggest you stay on that setup. FZD is soft, as the man above said, softer than LGY and that characteristic combined with Rosena gives that feeling. Good luck!
