What is the use of having an abstract fnc in the base class? I don't  
understand what you want to do. For calling these differently  
structured "overloads" you have to typecast your class to TA2 or so  
anyway, unless you declare all these variants also as virtual  
abstract methods in your base class (in which case your problem is  
immediately solved, but I don't really see the use of that because  
you can't have generic code when calling any of these methods anyway).
