Brushcountry I have the primos mini mag howler and diaphragm howlers. I also hit bad notes with the mini mag. I think I sound better on the diaphragm calls. I have always used rabbit distress calls. I am just trying to learn to howl at them so I can add to my bag of tricks. I had a Mac Daddy howler to I threw it away because the diaphragm went bad in it. So I guess I am also looking for a good howler.
