Quick Control Impressions (from a Lefty):
Like I have stated before, I don't have a CC Pro. So I'm playing with my right hand aiming and my left on the circle pad (I tried out the face buttons for movement.... yeah not too good). But I'm actually surprised at how accurate I still am with the right hand holding the stylus. Maybe it's because it only requires small movements, but it has worked pretty well so far. In fact, I would probably say that in the air I would stick with the current control scheme even if I had a CC Pro. I have trouble grasping movement with my right hand, so while I'm not as accurate with my right for aiming, I would be able to move a lot better which would even everything out (or maybe even give me an advantage).
As for on foot controls, things get tougher. I'm still accurate with my right, but I have trouble precisely turning around and controlling the camera. Though, interestingly, I tried out the face buttons for ground control with the stylus in my left, and I STILL had problems with the set-up. Maybe it was because of the cumbersome movement that is mapped to the face buttons, but I still couldn't get a grip on controlling the camera. So it makes me wonder, would my experience be any better with a CC Pro? Over time, probably. But I do think that us lefties can fully enjoy the experience without the add-on (considering most of us have come to terms with using the left hand for movement, and the right for camera control). So that is a good signs of things to come.
