Used by Olympic champion Ma Lin. My vote for the finest rubber in the world. Mark V is not slow, it is fast with great spin. It excels at close to table play with great touch for the short game as well as looping, hitting and quick counters. The speed to control ratio is high. No rubber is more consistent from sheet to sheet. Not as fast or spinny as tensors but more controlled speed. A great rubber for any player from beginner to pro depending on thickness. Update concerning spin. With Mark V used on blades with limba outer plies the spin is higher than expected. Play it with BTY M. Maze or Primorac and you have a spin machine. Loops have severe topspin. Those that think Mark V is to slow simply do not have the technique or arm speed to get the full potential. Having used most of the tensor rubbers including many Tenergy's I returned to Mark V with better consistency while still maintaining powerful loops and drives. The perfect inverted rubber. Update. I am an intermediate level player and have used everything in the book from very expensive composition blades to all 4 types of Tenergy's. Want more balls on the table with great control/speed/spin? Get yourself an ALL+ class blade and 2 sheets of Mark V max or 2.0, 3 layers of glue and you will have a racket from the gods. You know your not going to the Olympics so take my advice. Mark V is the absolute best classic rubber in the world.
