I think most people play with people who like the dead and fuzz less balls. They are the ones who say, "no, don't open a new can, these are still good!"... then they show you the drop test... holding the balls at shoulder height and dropping them to show you they still bounce as they say "see, these are still good, they only have a couple sets on them."
My reply as I pop open a new can, much to their dismay is, "nah, we're good enough for new balls... put those back in your bag for practice." They'll grumble and mumble, and once in a while I'll go along with their little game... but once a can is popped open, there isn't much they can argue about.
