Frank WakefieldMy General rule, always crack 'em out.
Exception #1... if card is to be offered for sale in the near future, leave slabbed. I've done this a few times.
Exception #2... I once left a card slabbed when I was going to give it to a kid. The kid actually knew of the player, so I tracked down a card to give him. The first one I found and bought was slabbed, I left it that way.
Other Exceptions... I'm sure there are some.
