An HS Strut small box call along with a custom box call of about the same size is the main ones I would never leave home without. I don't have and have never used mouth calls and I've never felt that hindered without any in getting a bird in if he wants to come in. I can use them for loud, long distance calling to get a bird started and I have my gun up close to where I can get down on it to shoot such that I can use those calls to bring them in close.
