Nver run the Haint, but I did pick up a K&H Hail Fire at Gander Mountain on sale. That particular call you use a duck feed call type of air presentation. Instead of fluttering the tongue, you say "tick-ticka-tickaa" as you run the call. The hands seem to create the deepness of the tone by creating a "sound chamber". Starts out with high air pressure and tapers off. Not sure if this will help with the Haint?
