Agree for Rasanter, though you could try R50 - keeping in mind that the playing characteristics are different, so whatever you mean by "beating" could be fulfilled, but most probably it won´t.
The hardest new Hexer (PowerGrip) is still a nice enough rubber that is fairly easy to play. t05 Hard is way more demanding, much harder but also superior in spin potential (although one might find it easier to generate spin with a softer rubber but I´m talking maximum potential with proper technique and armstroke, i.e. where t05 Hard belongs, in the hands of pros and semi-pros).
