Trackball user here, with a cheap wireless mouse siting on the desk for variety. I use my left hand most of the time so the right can stay on the number pad, arrows, and enter key. During my busy season I often work eighty hours in six days and then I will switch the trackball or sometimes the mouse to the right to give the left a break, depending on the task I am working on.
