Although many manufacturers claim to have rubber with the best characteristics of both Chinese and Japanese style rubbers, this rubber truly comes close. Usually a tacky topsheet needs a harder sponge or the rubber is too slow, but the Ultima sponge really gives it the extra power required to make it come off fast enough off the tacky topsheet. The JUIC 999 Ultima Elite is a fully Japanese made rubber, with VERY high spin abilities but still with enough offensive abilities to class it as an offensive style rubber.
