Monkey long pimple rubber features high aspect ratio pimples that are spaced widely apart. This design allows for maximum buckling of the pimples heads, offering excellent rotational development. The pimples necks are smooth, while the wide and slightly roughened heads contribute to significant spin generation. The rubber provides a controlled feel under light pressure, but the pimples heads yield to higher pressure, resulting in a soft touch. This controlled yet unpredictable nature makes it challenging for opponents. The sponge version includes a dampening sponge for a balanced and responsive playing experience without feeling overly "dead."
