I will give one of the DD's try is there a particular model you like?
Right now I'm primarily running one of the acrylic double reeds. I'm typically a single reed guy, but this call is effortless. I really think I could teach anyone to call ducks with this thing.
We've been hunting a lot of small water lately that doesn't require really reaching out to the birds. I'm not one to blow crazy hail calls to begin with. Find where the birds want to be and call just enough to build up their confidence and keep them interested.
