I've just purchased one each of Genesis II 2.0mm in soft and medium.
I've only tried the medium for a couple of hours, but my initial impressions are positive. Slightly tacky, faster than most Chinese style rubbers but still with good control. Quality looks good.
I was previously using Skyline 3-60 and this didn't require a great deal of adjustment, it's slightly harder and faster on more powerful shots, but slightly less tacky.
I had purchased the soft with a view to using it on my backhand, however pressing with my thumb I would say they both feel the same, which would be towards the harder end of medium and certainly not soft. Also they have the same code printed on the sponge : AHXF6061. Unless the pip structure is different I'm fairly sure there is going to be no difference between how the medium and soft sheets I have play, in fact I wouldn't be surprised if there has been some sort of error in the factory, either way I'm just going to save the 'soft' sheet and either use it when the medium wears out or use it as a forehand rubber on a back up blade.
