Can't tell you how a snood works, but have been using DSD's for a while and they are awesome! Yes more money but well worth it, I have had some great results with them.
If I were buying decoys I would invest in the DSD's.
With that said I always recommend a Jake and Upright Hen for starters, I do use a strutter but there is some learning curve with him and basically with decoys in general. Can't plan to just put them out and think turkeys will come running...
