Grass is the long pimple with the best ability to return topspins with heavy backspin. Close to the table you can decide to chop without or with significantly more backspin, than other pips heave. The attacking facilities are not that good, those of Chinese pimples are, but better as with almost all other Japanese pips. The pips are close to the allowed aspect ratio, smooth and soft. Significantly longer than Extra Long. Control and breaking effects are good enough for using ALL blades, but for heavy backspin and good chopping control WITH sponge, a defensive blade should be used. The rubber is one of the slowest pimples. It has not that much reversal, when returning chops, but from every distance one could produce deception by manipulating the spin. The rubber exists since about 25 years and was the further development of Feint. Butterfly countered with the Feint Long, that now isn´t allowed anymore.
