I'm with you here. I have given up on TanTennis reviews. I started shaking my head ever more often with his reviews. He's just all over the place, sometimes with very similar frames where he claims totally differen things. And the amount of times where one of the critics is "sometimes, the ball just flies" ... well guess what, that's on you, not the frame. If it were a frame problem, the ball would fly all the time.
Also, he and his buddy are way too much fan-boying on ever effing Prostock...it's just ridiculous. Talking about bias...
If you want a more professional review, I like Tennisnerd and/or Rackets & Runners way better. TennCom also has very interesting insights. All of them have also tested the GT98.
