I have always liked the diamond series of mouth calls by Primos. I use the piggyback triple also. It has a nice raspy sound. Bottom line is any call will work.A gobbler can't tell the difference between a Primos, Knight & Hale, and a Quaker Boy. It's more based on what sounds good to us. I believe we as turkey hunters sometimes try too hard to be perfectionests, but that's okay, because we love our passion.
