The balls that work best with Pascal Box are the highest quality balls.
The only balls that do not work well are balls that have very dense rubber. And these are usually the ones that are advertised as training or high durability.
This is because the normal balls we use for play get their performance from the combined work derived from the elasticity of the rubber and the internal pressure.
Normal quality balls have a rubber with a certain density and elasticity and a high internal pressure (approximately like a car tire).
Training balls have a much denser and harder rubber because it gets its performance, its rebound, in the rubber and not in the internal pressure. That is why they last longer, because the rebound does not depend on the pressure but on the rubber, but of course, this makes them harder, heavier and less tactile for the player...that is why they are for training and are not used in matches and never in championships.
In short, any quality ball, designed for the game, of whatever make and model, will work perfectly with Pascal Box.
The training balls, with a denser rubber (does not allow air to pass through) are not suitable.
Now you can invest in your favourite ball regardless of the cost because you will get the most out of it throughout its real life.
