Our roller is a piece of PVC, but we've been wrapping it with different materials . The result is usually the same, but when we wrap it with a lower friction material, it hardly catches at all. We are running the fisher price at all different speeds with a planetary gear box, but haven't calculated the surface speed. or roller contacts the ball about 3/4 or so of the balls height. We are using a continuous roller at the moment.
We have tried lower speeds but the result remains the same.
