Righty and use left hand at my office and right hand at home. CST trackball in both locations. Keeps the wear and exercise even across my left/right hands. Probably can't effectively play fast-twitch games with my left hand, but only took a couple weeks to get up to speed for normal PC work when I started using my left hand. Amusingly, I switched to trackball with my right hand from mouse after I'd already been using trackball with my left hand for a while - the muscle memory didn't transfer over, so I was more adept with my left hand for a few weeks until my right caught up.
