The manufacturer isn't helpful either, as they never provide any standard data on the air resistance of a ball at a given speed. One can only hope it has been sufficiently tested and that they've learned from the mistakes of the Jabulani...

Wow really educative post, my physics teacher tried to explain these things to me then. What’s your personal take on this? Does that mean some things become a lot more possible with new ball designs. Take for example, the spin on some passes or shots. Do you think these designs makes them easier or difficult over the years?
