Well, generally I like to have no smoke in the chamber when I'm done with my hit. If I don't use the hole, there is usually smoke left in there that will go stale or escape while I'm holding my hit. If your bong is a size such that one chamber is not very much, keep sucking and release the hole when you're about done inhaling, to clear the last of the smoke into your lungs.
