It’s a medium hard rubber which feels mostly medium when playing. Topsheet grip is very nice, so is serves and short game. Not so bouncy. Blocking is very controlled. Faster than Glayzer 09c which is slow for most. Very easy and consistent to loop but sometimes makes you feel it lacks the finishing power/spin. Very suitable for most intermediates.
Rozena is a medium-fast rubber with above average rating for all other attributes. Kind of a do-it-all rubber (not a defensive rubber). Hits, serves, blocks, short game, loops all can be done with great ease. But none can be done top-grade. Hardness is "medium". Speed-glue effect is less compared other modern rubbers.
I think it's well suited to intermediates, developing players or BH of many FH oriented players.
