Had a swing with the Nanoray 800 today. As a consumer, it didn't fit my taste, (was hoping for racket with a Ti-10/NS9900 specs)
Well, held the real thing with factory strings. It's just like the official Yonex chart which states it's a stiff flex racquet.
In other words, it's basically a NR700RP shaft with a different frame(head). Instead of fullerene, the material is a Titanium composite rename Sonic Metal.
I was dreaming to get that elusive extra stiff/even balanced Nanoray (indicated by the red arrow). Won't be reviewing this racquet anytime soon.
