I don't find the 93 to play stiffly at all, although I know the stiffness rating is a bit up there. I was coming from the Yonex 89T which gave me some arm and shoulder pain and tried the Blade after reading the TW reviews. No looking back so far after about 1 month, arm feels great (I played 8 times last week!).
It may be due to my string set up and tension? Because of my recent arm pain, I started out with gut mains at 55 and savage crosses at 52 and it feels quite comfortable to me.
I am planning on adding leather grips to make it a little more HL but otherwise I love these things (have 2).
