for what? i don't cow call much, and when i do decide to cow call with a diaphragm, i like the primos cash cow (not sure if they still make it, but you can really drop the volume and make any cow sounds at any volume)What are your favorite go to elk diaphragm calls? Something you always have on you. I've been using a Rocky Mountain black magic but haven't tried much else. So far I really like it.
