glad to hear you're having a WTF moment (what's that function). Suggestion  
would be index cards, each containing notes on a class. truly understand  
what each parent class is in which methods are to be overloaded. Then look  
at one child and understand how it. Work your way breadth first down the  
inheritance tree.
