If you have 2 rollers spinning in opposite directions (clockwise and counter-clockwise) with the higher roller spinning slightly slower than the bottom one, you'll get backspin because the 2 rollers both give energy to the ball. If you had just the bottom roller and a hood, you'd still get backspin, but that's because of the friction of the hood keeping the top of the ball from spinning as easily. So basically two rollers are better than one + hood because of more power given to the ball and less power needed (you don't need to overcome friction).
