How do you know there is rubber in there?How can you be sure that they didn't make you a 'normal' lam?He didn't charge you an extra penny for all that extra work?

Carbon kookaburras are fine at club level aren't they?? I thought you could use them until they were dead.As for a lam, who plays in a league where the umpires would:A) be able to spot one?B) do anything about it?
