Problem with this approach is that different batches need to be tested!Originally posted by jahlad
i sudjested something like this a while ago......best idea i thought of was at the next tournie you are at get somone to walk round and ask all the teams for say 20 balls, what brand they use etc
and also get contact details for them all.
test the balls and also contact all the teams to see if they had any staining that day
do this at a few tournies and you should have the culprit!
