DSG cottontail, dying jack, vole squeaks are my favorite distress sounds. I find myself using my turkey box call more often now. Just make the quickest loudest yelps like a turkey is being eatten alive. Had multiple coyotes run in so fast I couldn't stop them within minutes of playing it. Definatly want a shotgun for that instance.
I find you don't need to turn the foxpro up very loud either, start on low volume for the first 5 minutes then progressively work its way up. I think they get even more weery when the call is overly loud
