Ok call me crazy [:-] but I've been trying to hunt coyote with a muzzleloader for a couple of months now. I am somwhat new to coyote hunting, but here in Colorado (up in the mountains) I haven't even seen any.
Now to answer your question I'm using the Primos Hot Dog and Lil Dog for howling and distress calls, and also am using the Ki-Yi for distress. They seem to have a good sound. I'm just not sure what I'm doing yet, other than having fun trying. Hope this helps. Good luck.
