I'm using the R.A.T. 7 with the Qck+, nice and big, but my hand gets really tired after an hour or two. Looking for a hard mouse mat this time, but I don't have any experience with hard mats, so I'm looking for some recommendations. I thought about buying the Razer Ironcald, but I heard it has lots of problems with bending and wearing. I think Roccat has some good ones, but I don't really know what to choose from there. So im up for sugestions.
