Quite a lot of plastics absorb water to a greater or lesser extent. I guess it is this that is the problem, along with mixing up the age of the ball. If you have a box of balls in the cupboard, they will be consistent within the box, as they have all been stored the same, and be the same age. Buy a bag of lake balls, some will be newer than others, and some will have been immersed for longer too. There is no way they will perform coonsistently.
