Buzzard, to answer you question, I use both. E calls are kind of nice in that you don't have to move around alot blowing on a call. Mouth calls are kind of nice because you don't have to carry around the extra weight of an E call. Just depends on what kind of mood I'm in when I go out. I think most people use mouth calls just because they're easier, but both of them have worked for me. Actually, last time that I went out the only thing I use was a howler mouth call. I was doing a series of howls and pup wines and called in 3 at the stand.
