Also, for those that think the balls are not heavy enough, the rule on the ball states:

"not more than 453 g (16 oz) in weight and not less than 396 g (14 oz) at the start of the match"

Take a digital scale and weigh the ball in question. If it isn't in that band for weight, it isn't a legal ball.

If you are going to argue a point, at least get factual information to back up your side.....
