Only Practice with Billiard Balls

Billiard balls have a tolerance of 0.5g whereas snooker balls are only within 3g, making billiard balls much more consistent.

If you do not have a set of Billiard balls to use, take the white, yellow and a red and use these. However, it is better to practice Billiards with a good set of Billiards balls as snooker balls can react very strangely if the weights are different.
