RE: Favorite predator calls?
A quote from the movie Jeremiah Johnson-
"Get behind your horse and walk up there!"
"But they'll see my feet..."
"Elk don't know how many feet horse have!"
Coyotes cannot structure logic and the triggered response will be the same from nearly any small-game distress sound. I use a jackrabbit type sound when it's windy and I have issues getting my sound to carry... each call has it's time and place.
The Crit-r-Call alone will do just about everything you're after. If you really want other calls, along with the ones you have, I'd suggest some custom stuff with unique sounds. A howler is a good idea as well.
