It may be a brother of the regular RZ but the characteristics are quite different. The overall feeling of RZ-EH is more direct and less bouncy. Throw angle is medium-high, trajectory is longer, tackiness is 15%-20% lesser, weight is even heavier and sponge feels very much harder. Spin is still pretty high but slightly lower comparing to RZ. Speed deficiency of RZ is fixed by increased sponge hardness and this rubber can be a medium-fast spinny powerhouse if one has to capability to always hit it through. If not, the touch can at times be thick and mushy.
The weight of this rubber is uncommonly heavy so watch out for lopsidedness between front/back side if it is a factor to consider. The hard sponge of RZ-EH can properly compensate support for a softer/slower blade but the best blade synergy should be medium-soft to medium-hard depending on playing style. Not recommended for blade too stiff/low dwell.
