I checked out the City Mini GT (can't find a floor model of the double at our local stores) and loved the steering and the air-filled nubby tires. Does anyone with a toddler and a baby (on the way or already born) have an opinion about which of these two models is better. I think the GT is heavier, which cuts against spending the extra money. But the handling seemed smoother. I was by myself and in a hurry when I tried it, so I haven't had a chance to try the fold.
