Jeez - I should have paid more attention in physics but I don't get it. How could you possibly accelerate the ball to an initial speed greater than the speed on the edge? Happen to know any illustrative web sites?

The problem is very simple.
With single wheel shooters, the ball has to roll along the hood. When you make the edge of a rolling object move at 1x ft/sec, the object as a whole moves forward at 0.5x ft/sec.
With double wheeled shooters, the ball is just pushed through the two wheels. It doesn't have any backspin and leaves at a maximum velocity of 1x.
