I don't understand the need for large mousepads. I dont move my mouse more than 2" in any direction ever.
you sacrifice a lot of precision, especially in FPS games, with this kind of mouse sensitivity. back when i was regularly playing quake 3 it was recommended that you set your mouse to have about 6 inches of mouse movement in either direction for a 360 degree spin, so a 12'' wide mousepad would be the bare minimum. i know that some counterstrike players took it to even greater extremes, with mousepads that were 2 or 3 ft wide.
