why is the hammer strike taking over?

Now I am really confused as to what is right. I guess from these posts it depends on your local association. Two years ago when I stated we were taught the Hammer for all strikes, called, swinging and dropped 3rd strike. The swinging strike is a more casual hammer no verbal, called third strike is a sharp hammer with verbal and dropped third strike is a sharp hammer no verbal. But out of 45 umps there are only two of us that use the Hammer. Everyone else uses the point with turning head. I just want to be able to communicate clearly to the players and coaches. But I can see with diverse styles and mechanics players and coaches have to adapt to the umpires.
