This has been my set up of choice for several years. DB Blind and DSD decoys one Jake and one hen. The DSD Jake is every bit as good as a stuffer and a lot more durable. Been
Many a bird took a dirt nap after coming to investigate them sweet hen sounds.
About calling, a lot of folks would be better off not calling at all. Sometimes less is better, but there are times that you can call as loud and as often as you want with great results. Knowing when to do each depends a lot on the type of birds your hunting, i.e. Easterns, Rios ect.. Country, eastern hardwoods or Kansas plains to Florida swamps.
Ill be going to school again this year, gonna try for a Merrians, hope to complete my slam. Looking at eastern Wyoming or North West Nebraska. Always fun to hunt a new area and different species of birds.
