I just got a 3u tiger. With strings, cushion wrap, and overgrip (stock grip removed) it only weighs 90 grams so pretty light for a 3u. I haven't played with it yet, but just flexing the shaft by hand and swinging it around it doesn't feel flexible, but rather solid and stiff like a 100zz.
Never tried Ryuga 2 but compared with Astrox 88d pro 4U, I thnk AX90 Tiger is more flexible, easier to play with and much lighter. This is now my go to racket. It reminds 2 of my favorite rackets (N9II and ZF2 4U) bringing best parts of both (N9II's flex and ZFII's compact head) with a BP just in between (302mm vs 295 for N9II and >310 for ZFII) .
