I think you pretty much nailed it.
It's primarily only used in inclement weather or for some of the heavies that are really loaded full. 12R/30L can handle the 744s most of the time and they like to use that when possible. But with it now closed, I don't see the 744s and other heavies using anything other than 4/22.
