So I've found my style to be using a head light racket. I was wondering if the nanoray Z speed is still good. Other recommendations are still greatly appreciated.
The Z-Speed has never been a head light racket and most likely will never become one. Maybe you should look at the Nanospeed 9900 which has been re-released recently or at the NR900. The upcoming Nanoflare series also seems to tend towards more head light balance. Overall the trend across all manufacturers these days goes more and more away from really head light rackets.
headlight, headheavy.... this is too rough. why not measure paremeters of your current racket, head weight, total weight, balance. lets say your racket is measured to be 290mm balance, 84g, this corresponds to 36g headweight. now you can take scale to nearest yonex boutiq and see, how much heavier z speed is.
