The T25 is a rubber not made for the average player. It is a rubber for those who play a quick off the bounce and rely on spin placement. The spin on T25 is equal to the amount of T05 depending, when you contact the ball. It is a hard rubber to play if you do not have quick reaction or good consistency on spin. Just know it is a specialist rubber. Not made for everyone. It's like Koki Niwa play style rubber.
