There is only one model that is used for all four pylons. In computer programming making use of already existing resources is essential. Maybe the other parts for the choice - BadB etc - are in another package, but I'm not interested enough to go through them all. The thing is that the names of the models are not usually important. There is some logic (to let other people know what it's meant for), but in the end it still depends on the modeler and the programmer.
