Giant gloves and giant balls? What the hell. In my days, coach would pelt you with stones and pitchforks and whoever didn't get stabbed or concussion made the team.
I think using a baseball glove to train is poor practice because players except for the wicket keeper use their bare hands in a cricket match. I remember when I played school boy cricket and we even had catching practice with baseballs and our bare hands. These over sized balls are also ridiculous because I don't think it will help you to be a better catcher.
