I tried Rakza Z. My friend gave me his racket to check couple of shots. I didn't like it. To passive, dead etc. I wouldn't imagine for myself such setup on FH for sure. He played it on BH because it was good for serves receiving and open ups. For BH if someone likes it, ok, for FH as I wrote I can't imagine.
His setup was, BTY Grubba ALL, Rakza Z on BH, and Acuda S1 T on FH. Then change the blade to OSP Virtuoso OFF-, and played couple of trainings before new rubbers came. At this moment he has Gewo Codexx (BH) and Dignics 80 (FH), he is practicing now.
Of course it depends on skill, but I have few setups and change sometimes. Nittaku Acoustic with both Rozenas (like it), Primorac with Tenergies T05/T64 (like it, too but now have those 2 tenergies on Nittaku Acoustic and like it much more
) On Wednesday should come FZD ALC + 2 Dignics05 and I hope that would like it the best
I'm also wondering why is so many haters for Rozena's. It is really good rubber if someone would like to practice and increase skill with proper shot it is also destructive for opponent.
