There are a lot of good calls out there, but if I had to pick only one it would be a primos hyper-lip single. Primos makes some good calls. Their bugles are by far the easiest to blow and I realy like their hyper-lip calls. The hoochie mama is a great little call to have. I like to use it along with a hyper-lip so you sound like more than one elk. I have tried other calls and like I said there are other realy good calls out there I just personaly like the Primos line.
