RE: screaming that diaphram
I myself like getting loud with my diaphram. Especially if I have one gobbling at my calls a ways away. Once I have seen the gobbler or know that he is coming, I tone it down. I really like being aggressive, but I also know when I should tone it down. I use to be a run and gunner, but not so much anymore. I try to set up and call the birds. I really practice on patience while hunting...
