Hard and fast sticky chinese rubber.
Very offensive attacking rubber with abilty to put both speed and spin on ball with fine skill.
World number 1 Wang Liqin uses this rubber.
To control this spin wise you need refined and fine skill. You'd prob need to play 'at least' 2 times a week to control this thing with consistency, especially if like to use spin. So hard and fast that it is very hard to control spin wise on faster blade.
