I was in a windows store yesterday for pc crap, not gaming. I sat down to fiddle with a display pc. I wasnt there for the mouse but took notice really fast. There was a roccat kone xtd on a roccat taito. I have never felt something so smooth. I have a g500 on a standard pad. It was like a hot knife through butter. Thats my next set up granting its xim compat. None the less, the mousr was larger than my 500. I forgot what i was there for, the mouse was tripping me out. To bad you cant try on all mice.
