Mark,
I cannot speak for "tracking" as I can barely steer at 15' much less 100'. However, the surface area which is proportional to the drag goes up as the as the diameter squared whereas the lift goes up as the diameter cubed (minus any balloon weight). Thus, a larger balloon has a higher lift to drag ratio (see how I cleverly snuck in an indoor airplane term).
