I only use a howler after I hear the coyote howl first, even then I only do a lone howl once. If I want the coyote to stop I'll bark at it with the howler, that's about it for me.
I believe it's smarter in most cases not to start off with a howler unless you know what you are doing. More predators have been killed using rabbit sounds then howlers, must be something to that huh?
If I could have only one sound, it would sure in the hell be a rabbit in distress.
All this is just one old mans opinion.
