I am new to field hunting for waterfowl. I have about 20 goose decoys 12 hot buy shells and some floaters I bury the keel on. My question is should I buy a dozen cheep full bodies, or should I buy a quality goose call like a feather duster with a DVD to teach me how to use it. I am currently using a flute. lastly i will also be hunting ducks out of this spread, and hunt mostly with myself and maybe one other person. thanks for your help
