LOKI Arthur China is a relatively new tacky rubber with a slightly more porous sponge than the usual Chinese rubber. Somewhat faster than e.g. DHS Hurricane 3 NEO. The sponge is about 40-41 deg hardness. Very good grip and spin ability and the control characteristics are really sharp for such a fast Chinese rubber.
Speed : 11/13
Spin : 12/13
