A question unanswered in my mind:
 
Does a rudder extension and/or strake improve controllability in a stall situation where the top of the tail is in disturbed air?
 
As others have said, for normal operations you have plenty of rudder authority with the piston.   However, try doing a forward slip and see how much you can get out of it.....not much.   So there's not a lot of "extra" there should you need it to overcome some assymetric unexpected problem on your airframe.
