This long pimples rubber is a deceptive hitting/chop blocking rubber, it hits better with sponge, but it will be very effective if you can master hitting without sponge. The chop/block shots are best done without sponge and the 1.0mm sponge is acceptable. The long pimples rubber will lose its deception if the sponge is over 1.0mm. This rubber will still hit well even with a 1.5mm sponge.
