If you have the funds purchase your own set of snooker , billiard or pool balls. I say this as the club balls are usually not clean and also have a few balls that have been replaced including the white. If you can’t afford a set of balls definitely purchase an aramith tournament champion white.

Practicing with a light white is also not good practice as screw and topspin shots change a lot and you don’t want to learn how to play with non conforming balls.

If you do learn how to play with a light white if you ever play competition you will find a massive difference and will then need to learn how to play position again.
