The sounds and sequences I use are in constant flux. What I do when I get a vocal response, or a coyote approaching, or a coyote leaving, or multiples, after a shot etc...etc...etc.. just isn't predictable from stand to stand.
I'm not saying I can't see the value of starting the call and letting it run, or going to the work of developing a sequence and having it work. It's just not practical for me.
Calling to me is challenging. Part of that challenge is the need, at times, for quick thinking and adapting to the situation at hand. Keeps the brain rust from setting in.
Plus with the blinding, fat finger speed of a very slow turtle that equates to my computer/keyboard skills, I could make a lot of stands in the time it would take me to build a sequence.
To the Ops question. There are many opinions, as we have all developed ideas based on experience and information.
In the fall I try appeal to every coyote early in the stand . After the timid or young coyotes have had a chance, I get aggressive in the last half in case there's old, experienced, coyotes hanging back.
There is a switch coming soon. Signs that it has already started here. More pairs responding, coyotes getting more vocal. I get more vocal with them.
During breeding season I still use prey distress, but not as much.
I was surprised to see that Foxpro thinks March is the worst month to call. I love calling in March.
These are generalizations because as said, my calling is in a constant state of flux. Coyotes trigger to different stimuli often and sometimes rapidly. That's the challenge for me.
