I tried playing the graphene speed pro in stock. the frame is powerful for a 18x20 but as spinny compared to my ig radical pro. can easily rip flat forehand winners with the speed. it feels heavier than my current stick and sometimes i get trouble maneuvering it when out of position. although thicker beam and stiffer, i didn't get any elbow problem after 2 hours and its really quite plush and comfortable to rip the ball.
overall good racket. i need a bit of transition time. maybe i'll need to add weight to the handle.
